bug#22203: 25.0.50; # is treated as a comment character in shell-command arg

[Kaushal Modi]

Hi,

I need to run shell-command that has a hash character (#) in it.

Here's is a trivialized example of what I need to do

(shell-command "echo abc#def" "*abc*")

The above works in a terminal and also in the below build from master branch:

Build date        : 2015/11/12 12:45 Thu

commit 9dd7da9945c16aa343080a535ed74eeecf769fd1
Author: Juanma Barranquero <lekktu@gmail.com>
Commit: Juanma Barranquero <lekktu@gmail.com>

    * test/automated/keymap-tests.el: New test file

I get the output "abc#def" in both the cases.

But when I do the same in an emacs -Q session on the latest emacs
build on emacs-25 branch, the # is treated as a "comment char" and
everything after the # is not passed to the shell.

So

(shell-command "echo abc#def" "*abc*")

is treated as

(shell-command "echo abc" "*abc*")

I searched the log messages for "shell-command" here:
http://git.savannah.gnu.org/cgit/emacs.git/log/?h=emacs-25 but I did
not find a commit that could have caused this change.

Is this change intentional? If so, how do I pass "#" to the shell
using shell-command?

Thanks!
