font-lock in shell.el

[Nick Roberts]

Symptoms:


In the shell buffer the current prompt has its own face,
comint-highlight-prompt. After a command is entered, the new prompt has this
face, but the face for the old prompt is relegated to font-lock-string-face.
In earlier Emacsen this didn't happen and one can recover the original face by
toggling global-font-lock-mode off and then on again.

I don't think this change is intentional and, in any case, I think the old
behaviour is better than the current one.
