I believe you are right with this analysis, thanks.

Wouldn't it be best to always test for abbreviated file name if the
full file name fails to match? E.g., it could be that the user turned
on save-place-abbreviate-file-names for a while, then turned it off
(or vice versa), thus causing mixed file names in the saved history.
It would also make the code simpler, I think.
