[PATCH 2/9] remove String::ShellQuote dependency.

From
EWEric Wong <normalperson@yhbt.net>

<20051124074857.GC4789@mail.yhbt.net>
In-Reply-To
<20051124074739.GB4789@mail.yhbt.net>

use safe_pipe_capture() or system() over backticks where shellquoting may have been necessary. More changes planned, so I'm not touching the parts I'm planning on replacing entirely.
