[PATCHv4 0/2] Filename completion fixes

[Andrew Burgess]

After pushing my filename completion series I started working on
filename option support .... and promptly discovered a couple of
(minor) issues in the filename completion code.  Neither are huge, the
first is a regression, though not a critical one I think, and the
second issue is a problem that existed before my recent changes, but
still I think should be fixed.

The filename option support is not included in this series, but is in
progress and will likely be ready to post once these are merged.

In v4:

  - After replying to Tom's email I figured out how to reproduce the
    Linaro CI setup.  I then found I'd make a mistake in the test
    regexp, which I've fixed in this iteration.

In v3:

  - The good news is that the fix I added in v2 did seem to fix half
    of the Linaro CI regressions.  But I forgot that I had two
    different cases, one for a single completion, and one for multiple
    completions.  I only fixed the single completion case in v2.

    So, in this iteration I've also tried to fix the multi-completion
    case.  Hopefully this will make the CI happy.

In v2:

  - The Linaro CI testing highlighted an issue with the additional
    completion tets I'd added.  I guess depending on either how
    readline is configured, or the version of readline in use, we see
    different control characters emitted.  The v2 update extends the
    regexp to hopefully cover both cases.
