It's not a bug, it's a feature, going waaaaay back to the early versions of
grep-dctrl. It is caused by this conditional statement:
if (args.num_show_fields > 1) puts("");
in the output code. And incidentally, it is independent of the name of the
single field - I have no idea why you weren't able to reproduce this with
fields other than Description (I was able to reproduce it with Maintainer,
too).
I don't remember why I wrote it like that. Probably to make it more
"user friendly", $DEITY help me.
There's a lot to be said in favor of consistency of output format, but I am a
bit wary of changing longstanding practice, since there might be user scripts
relying on this behavior.
Any comments, anyone?
