Definitely not beginners questions!

Actually, LilyPond already tries to handle this tricky situation, see
http://lilypond.org/doc/v1.8/input/regression/out-www/collated-files.html#spacing-folded-clef.ly
and the example below. In your example, it doesn't help.
You could correct it manually, by doing the clef change somewhat
earlier in the bar:
        <f' a>1*3/4 \clef bass s4

If you remove your raggedright setting, you will see that the crescendo
actually is started at the first note, but offset to the right.
I haven't been able to find the property that changes this.

Anyone else on the list who knows the answer??
Is it intended behaviour or a bug?

Looks like a bug to me!
