    _______________________________________________________

Details:

It appears that in the current CVS version, -oi works only in the instance
where the supplied regular expressions are all in lowercase.  This patch fixes
this problem.

In grep.c, precede the line:

(*compile)(keys, keycc);

with:

if (only_matching && match_icase)
{
   char *keys_ptr = keys;
   while (*keys_ptr)
   {
      *keys_ptr = tolower(*keys_ptr);
      keys_ptr++;
   }
}
