bug#8000: 23.2; strange behavior of !$ in shell window

[Unknown]

In a shell (bash) window, if I type "echo x<enter>", the character "x" is echoed (as expected).

If I then type "ls -l !!<tab>" the complete previous command is added to the current line andwhat is executed is "ls -l echo x".  What _should_ have been execute is "ls -l x"

Please use a valid email address to report bugs. I cannot reply to your

Why is that what should have been executed? I thought `!!' was a tcsh
feature (making it kind of strange that it works in a bash shell at all
IMO...) that expands to the previous command, not the stdout of the
previous command. I'm not aware of any shell history expansion that
works in terms of the output of old commands. This would make no sense
in the majority of cases (eg cp etc).

Oh, I guess you meant to say '!$', like in your subject line, not '!!'.
Apparently this is tcsh's equivalent of bash's $_.
Maybe the history expansion of this isn't implemented (?).
Personally I'd just use $_.

What do I know... it works in 23.1 but not in 23.2. So it ought to be
easy to see where this went wrong.

forcemerge 7883 8000
stop

And in 23.3 it will work again because this is a duplicate of
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=7883, sigh.
