Re: Please support add -p with a new file, to add only part of the file

Yep.  A workaround is to use "git add -N newfile" before running
"git add -p newfile".

I imagine "git add -p '*.c'" should also offer to add hunks from
source files that git doesn't know about yet, too.

Here's a quick demo (untested) that might _almost_ do the right thing.
Unfortunately it leaves intent-to-add entries around even for files
the operator rejects.  Anyway, maybe it can be a good starting point
for playing around.

Hope that helps,
Jonathan
