I've just pushed the attached to make grep use gnulib's new
getprogname module instead of the classic "progname" module. This
means there is no longer the classic "char const *program_name"
variable, nor any need to call set_program_name.

Subject: [PATCH] maint: switch from gnulib's progname to getprogname module
* gnulib: Update to latest, for its new getprogname module.
* bootstrap.conf (avoided_gnulib_modules): Include the getprogname
module rather than the now-obsolescent progname.
* src/grep.c: Include "getprogname.h" rather than "progname.h"
and remove any use of set_program_name.
* tests/dfa-match-aux.c (main): Likewise.
* tests/get-mb-cur-max.c (main): Likewise.
* src/grep.c (usage, main): Use getprogname() in place of program_name.
