Saying that the feature does "not work well" on non-lenear history
is like the behaviour of the feature is "undefined" on such a
history.  Quite honestly, when you do not give a single filename,
the behaviour is "undefined", either, so I do not think we want to
say what happens when the pathspec you give matches a directory.
The feature only takes a single filename on a linear history.
Anything else the feature does is "undefined" random behavour.
