I have an env var, WWW=/home/www/felix, which I have always used with
tab completion without problems.
cd $WWW/ht<tab>ph<tab>20110318
would expand in steps
cd /home/www/felix/htdocs/
cd /home/www/felix/htdocs/photos/
cd /home/www/felix/htdocs/photos/20110318
But some recent bash upgrade has scuppered this. <tab> no longer
expands the $WWW; instead, it escapes the $, adds a space at the end,
and thinks itself clever.
cd \$WWW/ht ph
which does me no good.
I'll be danged if I can figure out any google-fu to search for this,
and 'bash help' and 'info bash' have done me no good either.
I do not know which specific bash upgrade changed this, since I don't
have very many of these env vars I used similarly. The current "bash
--version" is 4.2.8(2)-release, gentoo version is app-shells/bash-4.2_p8.

A possible culprit maybe the bash-completion package. Have you updated
that recently?

I haven't had bash-completion installed for years. I forget now what
I didn't like about it, but it's not in the picture now.

Your google-fu is strong. I bow in your general direction :-)

There is one useful note in that thread. ESC ctrl-e gets rid of the
backslash, and if you want to keep the $VAR as $VAR, backspace over
the terminal space and continue. Or you can ESC ctrl-e again, and
convert the $VAR to its value, so you won't need to repeat the single
ESC ctrl-e for each further <tab>. A tolerable workaround for now.
