Subject: 24.4; History malfunction by special directory names
Date: Tue, 21 Apr 2015 02:08:07 +0800

As i tried to edit some files within a directory named "c#", and used
eshell to call the compiler, I soon discovered that eshell's history
function had no entries by pressing <UP> or <M-p> even though there
should be some. This should be easily verifiable by creating a directory
with the name "c#" and switching working directory into it.

Furthermore, it would seem that the history record is written, but
cannot be read correctly, since as one move of the directory in
question, <UP> or <M-p> calls whatever I have typed when I was in there.

Confirmed on GNU Emacs 25.1.50.8 (1e8cd05).

Steps to reproduce:

emacs -Q
M-x eshell
mkdir -p ~/tmp/c#
cd ~/tmp/c#
<up>

Best,

Marcin
