It turns out that I am not the only Git developer capable of producing
an off-by-one bug ;-)

This patch series fixes a bug where we ignored single-character changes
at the end of the lines when trying to ignore white space at the end of
the lines.

I split the changes into two patches because the fix turned out to have
a much broader scope than the test (which demonstrates just a symptom):
the bug was not in the patience-specific part of the diff code, after all.

Johannes Schindelin (2):
  diff: demonstrate a bug with --patience and --ignore-space-at-eol
  diff: fix a double off-by-one with --ignore-space-at-eol
