Subject: 24.4; Eshell history substitution causes error
Date: Wed, 05 Nov 2014 11:45:07 -0800

I'm not entirely sure whether history substitution in Eshell is a
supported feature, but attempting to use it leads to an error. Steps to
reproduce (from emacs -Q, with debug-on-error set to t):

1. M-x eshell
2. cd /
3. ls bin
4. ^bin^usr

Expected result: output of "ls usr"
Actual result: stacktrace:

Debugger entered--Lisp error: (wrong-type-argument stringp 108)
  string-match("bin" 108)
  (if (string-match "bin" str) (setq str (replace-match "usr" t nil str)))
  (lambda (str) (if (string-match "bin" str) (setq str (replace-match "usr" t nil str))) str)(108)
  mapcar((lambda (str) (if (string-match "bin" str) (setq str (replace-match "usr" t nil str))) str) "lsbin")
  (lambda (lst) (mapcar (function (lambda (str) (if (string-match "bin" str) (setq str (replace-match "usr" t nil str))) str)) lst))("lsbin")

Thanks, installed in master (tho I used your previous patch for that,
since the latest one had more transmission-induced errors).
