[Pkg-emacsen-addons] Bug#900870: magit-annex: flaky autopkgtest

[Paul Gevers]

Source: magit-annex
Version: 1.4.0-1
Severity: important
User: debian-ci at lists.debian.org
Usertags: flaky

While inspecting regressions in autopkgtest results¹, I noticed that
your package magix-annex fails once in a while, without obvious changes.
As far as I checked, the error is always of the same kind ('user-error
"Not inside a Git repository"' example output copied below).

Could you please investigate and make your autopkgtest more robust?
Please contact me if you need help and you think I can provide that (I
am not subscribed to this bug).

Recent discussion of gating migration by autopkgtests on debian-devel²
noted that if this is going to work, and in particular if we are going
to *block* migration when it causes autopkgtest regressions rather than
merely delaying it, intermittent autopkgtest failures are likely to have
to be considered RC due to their impact on the tested package's
dependencies; for now I've filed it as important.
