I just got a possibly wrong idea today morning.  The error happens in
the case that some command, which changes the match data, is added
into a hook.  When the hook is executed, the match data is also
changed.  Now, if we could assume that _hooks shall not change the
match data_, we can save and restore the match data automatically when
we run hooks.  I am not sure about this assumption, though.

Adding `save-match-data' to functions one by one works, but it is
difficult to check all of the functions, and it is not the overall
solution.

How do you think?
