The effect of this change is visible in the patch to the test vector
in t4014; with a small change with long filename, it stops truncating
the name part too short, and also allocates a bit more columns to the
graph for larger changes. t4052 shows a similar change.
I replaced 4014 with 4052 in the first sentence, and dropped the last
sentence and re-queued the whole series.
Thanks for cleaning it up. Very much appreciated.
