Re: find-file-noselect needs save-match-data

      Finally, I knew it's in type-break, and then I knew
    the problem is caused by `find-file-noselect' which is put on
    `post-command-hook' and changes the match data.

I think it is a bug to expect the match data to be preserved across
`post-command-hook'.  Which code expects that?  We should fix that
code to protect itself.

However, I think `find-file-noselect' may as well call `save-match-data'
for the sake of other places it may be used.
