[Bug 1008380] Re: mutt -f =FOO<tab> and mutt -f +FOO<tab> are broken

[Marius Gedminas]

On Ubuntu 13.10, with bash-completion 1:2.0-1ubuntu3:

- mutt -f =U<tab> completes to mutt -f UNKNOWN-LIST

- mutt -f +U<tab> completes to mutt -f UNKNOWN-LIST

In both cases the prefix is lost.

Title:
  mutt -f =FOO<tab> and mutt -f +FOO<tab> are broken

Status in “bash-completion” package in Ubuntu:
  New

Bug description:
  Here are two closely-related bugs in Mutt tab-completion.  My muttrc
  sets folder=~/Mail, and I've a mailbox named UNKNOWN-LIST. I can open
  it by typing either 'mutt -f =UNKNOWN-LIST' or 'mutt -f +UNKNOWN-
  LIST'.  As you can imagine, that's more typing than I like.  I want
  tab-completion.

  Bug #1:  'mutt -f +U<tab>' completes to 'mutt -f UNKNOWN-LIST', i.e.
  it loses the leading '+'.  Fix:
