Re: convert-standard-filename on w32 does not preserve match-data?

[Richard Stallman <rms@gnu.org>]

    The code using convert-standard-filename probably already feels a bit 
    overloaded. convert-standard-filename is an "add on" to what one 
    actually tries to do and it is easily left out. Requiring the coder to 
    also add save-match-data seems like an unnecessary burden in this case 
    and I therefore think that convert-standard-filename should call 
    save-match-data internally.

That is how I see it.

There will be some cases where for speed it is better not to do
save-match-data.  But in many cases the cleanliness of adding it
is more important than the speed of omitting it.
