Today i got this by accident:
================================================================
openbsd-src.git-null: performing reduce
Checking out files: 17% (11410/65508) ^MChecking out files:
18% (11792/65508) ^M [..]
This is the output of my dumb arena-manager, which i append after
the first scissor for reference. (Maybe someone finds it useful.
It's a dumb sh(1) thing, i don't do shell scripting that often.)
I haven't actually tried it yet, but setting .quiet for
unpack_trees may stop this output. (Compilation succeeds,
though.) I still and *truly* have no idea of the git(1)
internals, so i may oversee .. just *any* thinkable side-effect.
Hope this helps a bit.
(Actual patch as response. Have a nice weekend.)
