Re: [PATCH] repo-config: support --get-regexp and fix crash

Not really.  The fix is clean-and-obvious, and is readily
applicable to "master" without being cooked in "next".  On the
other hand, --get-regexp may or may not be so; by conflating the
two, you are delaying the trivial and useful fix unnecessarily.

I already split the patch and applied the fix on "master", while
keeping the rest in "pu" (sorry, I ran out of patience to test
everything to put it in "next" -- will do so tomorrow).

It is usually a good idea to avoid making an otherwise good
clean patch a hostage to new features (intentionally or
accidentally).

	Strange thing I realized: A value is white-space-trimmed at the end
	only if the line does not end with a comment. This fact is accounted
	for in the new tests.

Thanks - a note like this helps me quite a bit, because I
usually apply e-mailed patches with --whitespace=strip, which
would have destroyed the test, leaving me scratching my head
without such a notice.
