* gunzip.in, zcat.in, zcmp.in, zegrep.in, zfgrep.in: New files.

* Makefile.am (EXTRA_DIST): Add them.
(bin_SCRIPTS, MOSTLYCLEANFILES): Add gunzip, zcat, zcmp, zdgrep, zfgrep.
(.in): Use GZIP_BINDIR as the location of gzip binaries, if it is set.
(check-local): Use GZIP_BINDIR.
(install-exec-hook, remove-installed-links): Make 'uncompress' an
alias for gunzip.
* gzexe.1: At least one arg is required.  Don't give cat as an
example, since gzexe refuses to compress cat due to a bootstrapping
issue.  List more utilities in this category.
* gzexe.in, zdiff.in, zforce.in, zgrep.in, zless.in, zmore.in, znew.in:
Report our name in usage.
* gzexe.in: Don't compress bash.  Don't use rmdir, so it's
OK to compress rmdir.
* gzip.c: Now requires that you compile with -DGNU_STANDARD=0 to
get non GNU-standard behavior.  We now build with GNU-standard
behavior by default, so that programs do not depend on the names
of their executables.
* zdiff.in: Don't depend on the name of the executable, as per
GNU standard.  Instead, rely on an internal --__cmp option.
Support ' in options.  Check for failures in subsidiary gzip
invocations.
* zgrep.1: Clarify compression issues.
* zgrep.in: Don't assume POSIX-style case syntax.  Remove unused var
have_optarg.
* zless.1: zless sets LESSMETACHARS now.

 .SH DESCRIPTION
-.IR  Zgrep
-is used to invoke the
+.I Zgrep
+invokes
 .I grep
-on compress'ed or gzip'ed files. All options specified are passed directly to
-.I grep.
+on compressed or gzipped files.
+All options specified are passed directly to
+.IR grep .
 If no file is specified, then the standard input is decompressed
 if necessary and fed to grep.
 Otherwise the given files are uncompressed if necessary and fed to
-.I grep.
+.IR grep .
 .PP
-If
-.I zgrep
-is invoked as
-.I zegrep
-or
-.I zfgrep
-then
-.I egrep
-or
-.I fgrep
-is used instead of
-.I grep.
 If the GREP environment variable is set,
 .I zgrep
 uses it as the
 .I grep
-program to be invoked. For example:
-
-    for sh:  GREP=fgrep  zgrep string files
-    for csh: (setenv GREP fgrep; zgrep string files)
+program to be invoked.
