[RFC] Allow '!' in program paths

[Klee Dienes <kdienes@apple.com>]

2002-02-06  Klee Dienes  <klee@apple.com>

         * fork-inferior.c (fork_inferior): Add '!' to the list of
         characters that need to be quoted when building a string for the
         shell.  Quote '!' specifically with a backslash, since CSH chokes
         when trying to evaluate "str!str".
