That is perfectly sensible (and should apply equally to non-"abort" cases, I think).

You may be right about other people's workflows which I forgot to
consider. I have noticed a lot of inconsistency in this tool wrt to
mergetool.keepBackup and mergetool.keepTemporaries. Perhaps this
change should hinge on the latter.
Would you agree with this rephrased statement (accompanied by matching logic)?
When mergetool.keepTemporaries is false or not set, these temporary files
should not remain when the mergetool operation is aborted.
Here is the wording from git help config:
mergetool.keepBackup
After performing a merge, the original file with conflict
markers can be saved as a file with a .orig extension. If this
variable is set to false then this file
is not preserved. Defaults to true (i.e. keep the backup files).
mergetool.keepTemporaries
When invoking a custom merge tool, git uses a set of
temporary files to pass to the tool. If the tool returns an error and
this variable is set to true, then
these temporary files will be preserved, otherwise they
will be removed after the tool has exited. Defaults to false.
I have another commit in the works to clean up consistency around the
keepBackup. I'll re-roll this one at the same time.
Phil

Aren't there cases where people "abort" so that they can have a
chance inspect them outside mergetool program? If there are no such
cases, then I would agree with your claim "should not remain", but
the proposed log message does not explay why it is sure that there
are no such use cases.
