I agree, I prefer comma separated.

The problem here is that those headers X-Keywords, X-Label, etc are not
standard, so everybody does whatever he wants with them. But on the
other hand, I need to make some assumption to be able to split the
labels.

This last patch makes 'X-Label' and 'Keywords' space separated, and
'X-Keywords' comma separated. For X-Keywords there is no "no spaces"
requirement. I did this according to what mu does

I hope this plays nicer with mutt, as Dima asked. But I may be wrong as
I did not have the time to look at mutt's sources and got the
information second hand, expecting Dima's feedback :)
