_Z_g_r_e_p is used to invoke the _g_r_e_p on compress'ed or gzip'ed
files. All options specified are passed directly to _g_r_e_p_.
If no file is specified, then the standard input is decom-
pressed if necessary and fed to grep. Otherwise the given
files are uncompressed if necessary and fed to _g_r_e_p_.
If _z_g_r_e_p is invoked as _z_e_g_r_e_p or _z_f_g_r_e_p then _e_g_r_e_p or
_f_g_r_e_p is used instead of _g_r_e_p_. If the GREP environment
variable is set, _z_g_r_e_p uses it as the _g_r_e_p program to be
invoked. For example:
for sh: GREP=fgrep zgrep string files
for csh: (setenv GREP fgrep; zgrep string files)
