xzgrep: Fix compatibility with old shells.
Running the current xzgrep on Slackware 10.1 with GNU bash 3.00.15:
xzgrep: line 231: syntax error near unexpected token `;;'
On SCO OpenServer 5.0.7 with Korn Shell 93r:
syntax error at line 231 : `;;' unexpected
Turns out that some old shells don't like apostrophes (') inside
command substitutions. For example, the following fails:
x=$(echo foo
# asdf'zxcv
echo bar)
printf '%s\n' "$x"
The problem was introduced by commits
69d1b3fc29677af8ade8dc15dba83f0589cb63d6 (2022-03-29),
bd7b290f3fe4faeceb7d3497ed9bf2e6ed5e7dc5 (2022-07-18), and
a648978b20495b7aa4a8b029c5a810b5ad9d08ff (2022-07-19).
5.2.6 is the only stable release that included
this problem.
Thanks to Kevin R. Bulgrien for reporting the problem
on SCO OpenServer 5.0.7 and for providing the fix.
