Given that sscanf splits things up by whitespace, I think LPub and LSynth
would misparse file names with blanks or tabs in them.
As I said, Willy has a good argument, and well worthy of consideration.
I think that as long as there is embedded white space is not allowed, the
change will be backward compatible and not cause problems (at least not for
LPub and LSynth).

I have no idea whether this could be worked into your sscanf usage, but it
is possible to read whitespace into strings with the scanf functions using
scanlists (sets of [valid] or [^invalid] characters). It’s not the
most elegant solution, but here’s a simplistic C example anyway:

Anyway, I would agree that there really need not be any whitespace in the
official part library filenames. However, I do find 8.3 character filename
limitations exceptionally archaic, and as an end user I do like to use
natural whitespace instead of hyphens or underscores in filenames (LDraw
models or otherwise). So, thought I’d share this C trivia just in case it
helps lead to an easier-ish solution.

Thanks!
I’ll use it.

That’s a nifty scanf trick. But don’t forget, you might still want
to trim leading and trailing
whitespace (tabs and space characters) from the parsed filename
(and maybe even surrounding quotes).
