I can see what I can do with these. Don't hold your breath, though.

Regarding update-ref --stdin (your 4.), I notice that the input format 
is very strict, so the solution is to allow an optional CR before the 
LF. I alread have a patch, but it skips all trailing space, which is 
probably too lenient. (I only needed the patch once for a debug 
sesssion, but there is no obvious breakage without the patch.)
