address@hidden: shell-script-mode gets lost in small repro]

[Richard Stallman]

[I sent this message a week ago but did not get a response.]

Would someone please try to DTRT, then ack?
Sometimes bugs like this are not feasible to fix, but I'd
like someone to at least try.

In GNU Emacs 23.0.0.1 (i486-pc-linux-gnu, GTK+ Version 2.10.11)
 of 2007-07-06 on helios
Windowing system distributor `The X.Org Foundation', version 11.0.70200000
configured using `configure  '--build' 'i486-linux-gnu' '--host'
'i486-linux-gnu' '--prefix=/usr' '--sharedstatedir=/var/lib'

Important settings:

Major mode: Shell-script

Minor modes in effect:
  show-paren-mode: t
  pc-selection-mode: t
  global-auto-revert-mode: t
  auto-revert-mode: t
  delete-selection-mode: t
  tooltip-mode: t

  font-lock-mode: t
  global-auto-composition-mode: t
  auto-composition-mode: t
  auto-compression-mode: t
  line-number-mode: t
  transient-mark-mode: t

Type the following in a buffer in shell-script-mode:

#!/bin/bash
while false ; do
    echo "server $(hostname), $(date)" |
    mail -s "Alert: Almost out of disk space $usep%" $ADMIN
done

Note that shell-script-mode gets lost at the "mail" line, thinking it
is some kind of pre-formatted text.  Really obvious in font-lock-mode,
or if you try to indent the "mail" line using TAB.

Removing $(date) from the line before works around the problem.

Additional info: After typing in the whole script, you may have to
type a space at the end of the "echo" line to trigger the
lost-getting.
