Font-locking and single quotes in shell script mode

[Romain Francoise]

This change:

2005-11-27  Stefan Monnier  <address@hidden>

        * progmodes/sh-script.el (sh-font-lock-syntactic-keywords): \ doesn't
        escape single quotes.

causes a bug in sh-mode when the file contains something like the
following:

| $ cat foo.sh
| #!/bin/sh
| echo Don\'t do that
| echo "Let's do that instead"
| $

The single quote on the second line messes up fontification of the rest
of the file up to the next single quote.  Reverting sh-script.el to
revision 1.172 makes this test case work again.

Thanks,
