skip_multibyte_char()

[Christopher R. Hertel]

Jeremy,

Almost done with mangle.c.  I have a question:  Can mangled names ever
contain multi-byte characters?

In the original, Andrew does a simple test:  If there is an extension
on the *long* name and it is less than three (lower case) characters
long, then he strips off the extension.  In the reverse mapping, then,
he can reverse map a base name and add the short (dos-approved)
extension back on.  The result is that the cache contains a "group"
reverse map, which can be used for a whole set of names (eg.
'mangled.*').

  p = strrchr( mangled_stack[0], '.' );
  if( p && (!strhasupper(p+1)) && (strlen(p+1) < (size_t)4) )
    *p = 0;

Anyway, I'm being a tiny bit more careful, and saying that the
extension of the mangled name (converted to lower case) *must match*
the extension of the long name.  This is correct, basically, as the
original test (above) implies the same thing, but does not test it
explicitly.

Anyway, I just want to avoid being bitten by multi-byte characters, if
they even *are* an issue (don't think so, but I always like to check).
