[PATCH] sort.c: Fix minor memory leak, monthtab is never free'd if HAVE_NL_LANGINFO is defined and we're not in the "C" locale

[Joey Degges]

Hello,

At sort.c:1137, in inittables(), monthtab[i].name is alloc'd
if HAVE_NL_LANGINFO is defined and we're not in the "C" locale.

This patch adds the function freetables() which frees monthtab[i].name if
the appropriate conditions are met. freetables() is called at the end of
main().
