FYI: fix "make po-check" failure

[Jim Meyering]

2006-10-19  Jim Meyering  <address@hidden>

        * Makefile.maint (po-check): This rule didn't detect the new use
        of "gettext" (as opposed to the use of "_" everywhere else) in
        lib/xstrtol.h.  Adjust the grep regexp so that now it does.
