[Pkg-zsh-devel] Bug#807906: zsh-common: Command completion broken since aptitude 0.7.5

[Micha Moskovic]

Package: zsh-common
Version: 5.2-2
Severity: normal

Dear Maintainer,

since updating aptitude to version 0.7.5-1, the command completion for aptitude
is broken.
Pressing tab after writing aptitude on the command line has the following
result:

$ aptitude <Tab>
 -- no matches found --

while it would print the list of available commands in previous version of
aptitude.
Note that option completion ($ aptitude -<Tab>) and package completion ($
aptitude install <Tab>) still work.
I believe that this is due to one of the following changes in aptitude 0.7.5-1
(from the changelog)

    - User visible changes:
      * [cmdline] Minor improvements to help (Closes: #497136)
      * [cmdline] Hide Show-Why reasons when the string is empty
        (Closes: #576584)
      * [cmdline] Slightly improve and reformat --help
      * [cmdline] Document add/remove-user-tag in --help

given that the output of 'aptitude -h' is parsed in order to provide the
command completions.
Line 83 of Completion/Debian/Command/_aptitude probably needs to be modified in
order to account for those recent changes in aptitude.
