Re: [PATCH 0/1] sequencer: comment out the 'squash!' line

the end result would have a log message for a single commit that
describes the single thing it does, which would not resemble to the
original of any of the squashed message---and removing extra title
lines would be the smallest part of such an edit.  So...
