Merge branch 'nd/completion-no-cache-failure'

An incorrect list of options was cached after command line
completion failed (e.g. trying to complete a command that requires
a repository outside one), which has been corrected.

* nd/completion-no-cache-failure:
completion: do not cache if --git-completion-helper fails
