[Bug 655849] Re: /etc/bash_completion.d/mutt quotes tilde which cannot be expanded by bash (or: why is query_command invoked at this place at all?)

[Peter Cordes]

not reproducible on trusty.  I have mutt installed, but my mailserver is
an old Debian box that I ssh to and run mutt on, so I don't have
anything but the default mutt setup to test with easily on current
Ubuntu.

reopen if this is still actually broken.

Title:
  /etc/bash_completion.d/mutt quotes tilde which cannot be expanded by
  bash (or: why is query_command invoked at this place at all?)

Status in bash-completion package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: bash-completion

  Expected vs observed behaviour
  ==============================
  When typing
  $ mutt -f =k<TAB>
  bash-completion should offer mailboxes starting with "k"

  Instead, bash gives the error message
  $ mutt -f =kbash: ~/.mutt/muttquery: No such file or directory

  Bug 1: Completion produces a bash error
  Bug 2: Completion executes mutt's query_command, which is intended for retrieving email addresses, not mail boxes

  Analysis
  ========
  - Pressing <TAB> invokes bash completion, which calls "_muttquery" from /etc/bash_completion.d/mutt
  - "_muttquery" calls "mutt -Q query_command", which in my case returns the string
  query_command="~/.mutt/muttquery '%s'"
  - "_muttquery" extracts the substring "~/.mutt/muttquery '%s'" (without surrounding quotes), replaces %s by "'\''k'\''" (without surrounding quotes), and then executes the bash command
  '~/.mutt/muttquery' ''\''k'\'''

  Since the tilde is quoted by single quotes, bash does not expand it to
  the home dir, but interprets it literally. Hence the observed bash
  error message.

  Bug 1: Completion should not single-quote tildes which are expected to be expanded by bash.
  Bug 2: Completion should not call _muttquery since there is no mail address expected after "-f ="
