If anyone still has a reproducer environment setup with a patch bash
version on precise and can easily reproduce please feel free to do so
and alter the description above. In the meantime, Ill get a reproducer
setup and update the description once my test is done.
Thanks

** Description changed:
Binary package hint: bash
+
+ [Impact]
+ Bash-4.2 tries to leave completed directory names as the user typed them,
+ without expanding them to a full pathname. One effect of this is that
+ shell variables used in pathnames being completed (e.g., $HOME) are left
+ unchanged, but the `$' is quoted by readline because it is a special
+ character to the shell.
+
+ [Test Case]
+ - [Current test case showing expected behavior]
+
+ Items to address so far:
+ - that $ is escaped less
+ - that direxpand does not expand as expected
+ - that direxpand option is available and if enabled, expands directories
with variable names.
+
+ - [Previous Test Case showing non-working bash installation]
~$ mkdir -p /tmp/testd/finger/toe
/tmp$ cd /tmp/testd
/tmp/testd$ td=`pwd`
/tmp/testd$ cd ../
/tmp$ ls $td/fing
Type a TAB character at this point, and bash completion makes the line:
- /tmp$ ls \$td/finger
+ /tmp$ ls \$td/finger
Note that while 'fing' has been expanded to 'finger ' (with a space at the
end), the $td variable reference has had the
$ character quoted with a backslash. This prevents further extension of the
pathname, and in fact makes
the command invalid; if I type a newline at this point, I get:
ls: cannot access $td/finger: No such file or directory
This is not useful behavior. I believe that in Ubuntu 10.10, the $td
variable would have been expanded
to '/tmp/testd', and subsequent completions starting from
'/tmp/testd/finger' would have worked.
-
- [The version of /etc/bash_completion.d/acroread.sh that is installed starts
with:
+ [The version of /etc/bash_completion.d/acroread.sh that is installed
+ starts with:
# _filedir : to handle file and directories with spaces in their names.
if ! type _filedir &> /dev/null ; then
so I don't think that file is overriding /etc/bash_completion's _filedir
...]
