The main reasons are to avoid noise in patches, prevent patch corruption
when sent over email, and IMO it's just good practice (ie. what people
contributing code would expect). If we don't care about this, then why
care about spaces vs. tabs, spaces before function parameter braces,
indentation, and so on?
Also, I'm not suggesting that we reject code solely because of trailing
whitespace, just that it become something the developers do; I would
guess that the vast majority of what I removed in that commit was caused
by Geany developers themselves.
It takes two seconds to turn the stripping feature on in Geany or Git
and it automatically handles the "bug" in Geany's auto-indent where it
adds the indentation when you press enter but doesn't remove it when you
leave the line blank. This is where the bulk of the trailing whitespace
came from. As of for the extra newlines at the end of files, I think
those are caused by a "bug" in one of the processing scripts used on
Geany's source code (fix-alignment.pl:91 maybe).
If you really feel strongly against this, I honestly don't mind if you
revert the commit and we can just forget about it altogeher. FWIW, I
did check with Colomban about this, confirming that there shouldn't be
trailing whitespace and that it was ok to commit this, before doing so.
Sorry for such a long response to something so trivial :)
