Nothing is quoted. Your string acts as if it was XXX in:
sh -c 'XXX'
so any quoting is entirely on your own. Thus, without the multi-arg exec in
my proposed replacement, you can get shell-ish interactions that can ruin your
day pretty bad.

The Perl $variable is expanded to its current contents. But suppose the
contents are `date` (including the backquotes). That would mean that a shell
would execute a date command, and *its* output would then contribute further
to the command invocation.
