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

[Richard Stallman]

    `save-match-data' is not cheap.  I suppose it's not advisable to
    automatically wrap every hook into it.

Not every hook.  On the other hand, find-file is slow, so a little
extra slowness in find-file is not a problem.

    I think that `find-file-noselect' and `file-truename' should not change
    match-data regardless of whether they run in a hook or not

I agree, expecially for `file-truename'.
Functions that just manipulate file names ought to be made easy
to call without worries.
