Thanks for a patch.

We prefer to cite an existing commit with its title and date these
days, not just with its object name.

    Since 7cb6ac1e ("diff: diff_aligned_abbrev: remove ellipsis after
    abbreviated SHA-1 value", 2017-12-03), the "--raw" format of diff
    does not add ellipsis in an attempt to align the output, but...

or something like that.  Note that saying this is about the raw format
is quite essential thing to tell the readers to explain this hange.

Yeah, I do not think it makes sense to use the workaround that is
planned for removal, which will later make us revise the example in
the documentation again, to end up with the text that you have right
now.  I do not think this three-line paragraph needs to be in the
log message, either, though.  Perhaps below the three-dash line.


Also please sign-off your patch here (see
Documentation/SubmittingPatches).
