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

    Apropos: it appears to have been lost in the noise: save-match-data in
    its current implementation is _not_ a noop around code not touching
    match-data, since it converts integer data into markers (which move
    their positions under buffer changes) and then back again.  Is there a
    compelling rationale for that?

I am sure it was done to fix a bug, and I can imagine what the bug
looked like.
