Yes, unless further fontification is done after insertion.

Because I think the inheritance of face for overlay strings
is a task
of face merging in the redisplay code, I'm not doing
anything special
about it in the TSM support code.  The redisplay code just
behaves
like this (i.e., inherit the face just after one marker of
the
overlay).

One idea would be to change the behavior by which property
we use,
before-string or after-string.  If we regard an overlay as a
modifier
for an interval, it would be natural for before-string
(after-string)
to respect the face that is attached to the first (last,
respectively)
character of the interval.  Of course, some consideration is
needed
for special cases such as empty intervals, and it might not
be a good
time to make such a change.
