I do think it would be helpful to introduce that helper, especially if
it is useful in this patch series.  There seem to be enough other
places where it can be useful to make it worth adding the helper.

The commit message should also describe why we need this preparatory
step. Maybe something like:

      To reduce the noise in when refactoring this pipeline in a
      subsequent commit fix the indentation.  This has been wrong
      since the refactoring done in 1b5b2b641a ("t0000: modernise
      style", 2012-03-02), but carries no meaning.

Out of curiosity, how did you create the patch?  'git format-patch'
would add a '---' line followed by the diffstat, where you would
usually put the commentary that you put before the scissors line.  It
seems like 'git am' still handles this fine, which I didn't know, just
something I noticed because I'm used to the other format.

Since this patch series is now 5 patches, that commentary should go
into a cover letter (see the --cover-letter option in format-patch),
so the reviewers can read that first, and read the patches with that
in mind, focusing on the patch only, and not additional commentary
that applies to the whole series when reading the patch.
