tab expansion of $HOME/ to \$HOME/

[Diggory Hardy]

Hello,

I'm using this version of bash:

$ bash --version
GNU bash, version 4.2.45(1)-release (x86_64-redhat-linux-gnu)
Copyright (C) 2011 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>

on Fedora 20.

If I enter

$ ls $HOME/Do

and press the Tab key, bash expands to

$ ls \$HOME/Documents

(notice $ is replaced with \$). This is from my point of view an annoying 
anti-feature, since I must then remove the escaping back-slash. What's going 
on?

I should state that the only reason I noticed this is that I don't have a ~ on 
my current keyboard, but still this seems like a valid bug report to me.

Best regards,

Diggory Hardy
