Bash Version: 4.2
Patch Level: 8
Release Status: release

Description:
        echo $PWD/<TAB>

expands to
 
        echo \$PWD/

which is *wrong* (and does not work neither for futher file name completion nor 
for calling whatever with the real directory path as argument).

same happens with 4.2.10 (opensuse 12.1 beta-test), but works fine with 
bash-3.* and bash-4.1 

for my opensuse bug report see

Repeat-By:

type    echo $PWD/<TAB>
