15ec2a04f8 When called as `zgrep', the -Z argument is assumed. Make a
link from zgrep to grep.

a6f4e3c4dc Added builtin decompression using zlib library, option -Z.
Enabled this new feature with the makefile variable GREP_LIBZ. If
you don't like it, compile with `make GREP_LIBZ='.

grep + zlib has several advantages:

- the shell script zgrep(1) will be basically a one line
  exec grep -Z "$@"

- no shell script, no bugs. The current zgrep implementations
  have many bugs and some grep options are no supported.

- no shell script, no security risks.

- it is a magnitude faster than a shell script

Also fixed:
0 -> STDIN_FILENO
Close a file descriptor only if the open call was successfully. It does
not hurt for the open(2) function, but the gzclose(3) function
died in free() to free up (not) allocated memory.
