I'm revising old Emacs bugs in Debian and will forward some of them that
still apply.  To reproduce this one:

emacs -Q

M-: (start-process "nop" (current-buffer) "sleep" "100")

In the *scratch* buffer, type "free", then with point after that word

M-x hippie-expand

Result is the error

Symbol's value as variable is void: comint-use-prompt-regexp

A possible solution is to (require 'comint) in hippie-exp.el.

Subject: Bug#169137: emacs21: try-expand-line-all-buffers broken in hippie-expand
Date: Thu, 14 Nov 2002 13:02:02 -0800
Message-ID: <20021114210157.GA12341@barsoom.org>

Package: emacs21
Version: 21.2-1
Severity: normal

I recently started using the hippie-expand package, but there seems to
be a bug in the try-expand-line-all-buffers function.  Here's the
relevant bit of my .emacs:

(global-set-key "\M-/" 'hippie-expand)
(setq hippie-expand-try-functions-list 
     '(try-complete-file-name
       try-expand-all-abbrevs 
       try-expand-line
       try-expand-line-all-buffers 
       try-expand-list try-expand-list-all-buffers 
       try-expand-dabbrev-visible
       try-expand-dabbrev try-expand-dabbrev-all-buffers
       try-expand-dabbrev-from-kill try-expand-whole-kill))

When I do an expansion, I get this in my *Messages* and the expand fails:

apply: Symbol's value as variable is void: comint-use-prompt-regexp-instead-of-fields

If I comment out try-expand-line-all-buffers, everything works fine.
It also works if one of the earlier expansions finds a match.
