Bash Version: 4.2
Patch Level: 10
Release Status: release

Description:
        typing 'echo $PWD/[TAB]' results in 'echo \$PWD/' instead of
        'echo <current-path>/'
        (all without single quotes of course...)

        This behaviour doesn't exist at least in bash-4.1.5

        ( bash-4.2.10 comes here with ubuntu-11.10,
          bash-4.1.5 comes here with ubuntu-10.04 )

        Copying old version of bash to new system brings right
        behaviour. If you think the new behaviour is right, then
        there should be an easy way, to revert it by an option,
        because at least for me bash-4.2.10 is unusable with this
        behaviour.

Repeat-By:
        see above.

Fix:
        revert to old behaviour or make it configurable at run-time

For questions or replies please use my eMail directly, because I'm
currently not reading any bug-lists for bash.

best regards
