+/* General:
+
+       It's necessary to parse up the format string to recognise the GMP
+       extra types F, Q and Z.  Other types and conversions are passed
+       across to the standard sscanf or fscanf via funs->scan, for ease of
+       implementation.  This is essential in the case of something like glibc
+       %p where the pointer format isn't actually documented.
+
+       Because funs->scan doesn't get the whole input it can't put the right
+       values in for %n, so that's handled in __gmp_doscan.  Neither sscanf
+       nor fscanf directly indicate how many characters were read, so an
+       extra %n is appended to each run for that.  For fscanf this merely
+       supports our %n output, but for sscanf it lets funs->step move us
+       along the input string.
+
+       Whitespace and literal matches in the format string, including %%,
+       are handled directly within __gmp_doscan.  This is reasonably
+       efficient, and avoids some suspicious behaviour observed in various
+       system libc's.  GLIBC 2.2.4 for instance returns 0 on
+
+	   sscanf(" ", " x")
+       or
+	   sscanf(" ", " x%d",&n)
+
+       whereas we think they should return EOF, since end-of-string is
+       reached when a match of "x" is required.
+
+       For standard % conversions, funs->scan is called once for each
+       conversion.  If we had vfscanf and vsscanf and could rely on their
+       fixed text matching behaviour then we could call them with multiple
+       consecutive standard conversions.  But plain fscanf and sscanf work
+       fine, and parsing one field at a time shouldn't be too much of a
+       slowdown.
+
+   gmpscan:
+
+       gmpscan reads a gmp type.  It's only used from one place, but is a
+       separate subroutine to avoid a big chunk of complicated code in the
+       middle of __gmp_doscan.  Within gmpscan a couple of loopbacks make it
+       possible to share code for parsing integers, rationals and floats.
+
+       In gmpscan normally one char of lookahead is maintained, but when width
+       is reached that stops, on the principle that an fgetc/ungetc of a char
+       past where we're told to stop would be undesirable.  "chars" is how many
+       characters have been read so far, including the current c.  When
+       chars==width and another character is desired then a jump is done to the
+       "convert" stage.  c is invalid and mustn't be unget'ed in this case;
+       chars is set to width+1 to indicate that.
+
+       gmpscan normally returns the number of characters read.  -1 means an
+       invalid field, -2 means EOF reached before any matching characters
+       were read.
+
+       For hex floats, the mantissa part is passed to mpf_set_str, then the
+       exponent is applied with mpf_mul_exp or mpf_div_2exp.  This is easier
+       than teaching mpf_set_str about an exponent factor (ie. 2) differing
+       from the mantissa radix point factor (ie. 16).  mpf_mul_exp and
+       mpf_div_2exp will preserve the application requested precision, so
+       nothing in that respect is lost by making this a two-step process.
+
+   Matching and errors:
+
+       C99 7.19.6.2 paras 9 and 10 say an input item is read as the longest
+       string which is a match for the appropriate type, or a prefix of a
+       match.  With that done, if it's only a prefix then the result is a
+       matching failure, ie. invalid input.
+
+       This rule seems fairly clear, but doesn't seem to be universally
+       applied in system C libraries.  Even GLIBC doesn't seem to get it
+       right, insofar as it seems to accept some apparently invalid forms.
+       Eg. glibc 2.3.1 accepts "0x" for a "%i", where a reading of the
+       standard would suggest a non-empty sequence of digits should be
+       required after an "0x".
+
+       A footnote to 7.19.6.2 para 17 notes how this input item reading can
+       mean inputs acceptable to strtol are not acceptable to fscanf.  We
+       think this confirms our reading of "0x" as invalid.
+
+       Clearly gmp_sscanf could backtrack to a longest input which was a
+       valid match for a given item, but this is not done, since C99 says
+       sscanf is identical to fscanf, so we make gmp_sscanf identical to
+       gmp_fscanf.
+
+   Types:
+
+       C99 says "ll" is for long long, and "L" is for long double floats.
+       Unfortunately in GMP 4.1.1 we documented the two as equivalent.  This
+       doesn't affect us directly, since both are passed through to plain
+       scanf.  It seems wisest not to try to enforce the C99 rule.  This is
+       consistent with what we said before, though whether it actually
+       worked was always up to the C library.
+
+   Alternatives:
+
+       Consideration was given to using separate code for gmp_fscanf and
+       gmp_sscanf.  The sscanf case could zip across a string doing literal
+       matches or recognising digits in gmpscan, rather than making a
+       function call fun->get per character.  The fscanf could use getc
+       rather than fgetc too, which might help those systems where getc is a
+       macro or otherwise inlined.  But none of this scanning and converting
+       will be particularly fast, so the two are done together to keep it a
+       little simpler for now.
+
+       Various multibyte string issues are not addressed, for a start C99
+       scanf says the format string is multibyte.  Since we pass %c, %s and
+       %[ to the system scanf, they might do multibyte reads already, but
+       it's another matter whether or not that can be used, since our digit
+       and whitespace parsing is only unibyte.  The plan is to quietly
+       ignore multibyte locales for now.  This is not as bad as it sounds,
+       since GMP is presumably used mostly on numbers, which can be
+       perfectly adequately treated in plain ASCII.
