I'm leery of introducing this kind of change into comint.el at this
stage in the release.  It doesn't seem to fit Richard's criterion of
being "simple and safe".

BTW, I can't seem to reproduce the problem referenced in the original
bug report.

M-x shell RET
~ $ cd /tmp/
/tmp $ mkdir /tmp/'(2007)'
/tmp $ cd \(2007\)
/tmp/(2007) $ pwd

 => /tmp/(2007)

This is GNU Emacs 22.0.95.3 (i686-pc-linux-gnu, GTK+ Version 2.10.6)
of 2007-03-04.  Could this be a shell bug on certain systems?
