[Bug 778627] Re: In natty, bash completion now quotes shell variable references rather than expanding them

[Dmitrijs Ledkovs]

@Alec Warner (antarus):
The proposed patch is ok, sans missing this bug reference and not using correct SRU version number. But that's easy enough to fix when sponsoring. Please update bug description as per SRU guidelines if you want this uploaded in Precise. Thanks.

  In natty, bash completion now quotes shell variable references rather
  than expanding them

Bug description:
  Binary package hint: bash

  ~$ 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 

  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:

  # _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 ...]
