(hard_LC_CTYPE): Remove.
(keylist): Renamed from keyhead. Now a pointer, not a
mostly-unused struct. All uses changed.
(findlines, keycompare, CMP_WITH_IGNORE, compare, checkfp, mergefps,
sort): Tune and use a more consistent style for reallocation.
(keycompare, main): Don't worry about LC_CTYPE;
it's buggy with multibyte chars anyway.
(compare): Invoke alloca (0) after each call to keycompare,
not just the ones that return nonzero. This avoids a memory
leak on architectures without builtin alloca that occurs
sometimes when a file contains all duplicate lines.
Don't use SA_INTERRUPT to decide whether to call sigaction, as
POSIX.1 doesn't require SA_INTERRUPT and some systems
(e.g. Solaris 7) don't define it. Use SA_NOCLDSTOP instead;
it's been part of POSIX.1 since day 1 (in 1988).
