Aha, missed that there is indeed a testsuite - nice!

It does not look like dead code to me.

I don't have a strong opinion. I started with '-b 123,245', believing
that the syntax is fine. But then I realized that without '-p'
specifying multiple '-b' looks better by having multiple '-b' if 'PR
<component>/'  (needed for -p as the string is than taken as is). Thus,
I ended up supporting either variant.

But I also happily drop the ',' support.

Change: One quote change, one test_mklog update.
