[bug-grep] patch to fix a rare problem with consts, second attempt

[Stepan Kasal]

[I have to apologize, I've forgotten to attach the patch.]

Hi,
  Bruno Haible has mailed me the patch attached to this mail.
Here is his original explanation:
--- Bruno ---
When I build the grep CVS on MacOS X [it appears to depend on the gcc
version] with

  $ CC=gcc CPPFLAGS=-Wall ./configure --disable-nls
  $ make

I get a warning about 'const' being cast away from the return statements
in kwset.c:kwsincr(). The reason is that in this case
  return _("memory exhausted");
expands to
  return "memory exhausted";

The caller is obviously not meant to destructively modify the returned
error message. Therefore the right fix is to change the return type.
--- end ---

I wasn't able to reproduce the problem, but I think there is no problem
with this patch.
