[PATCH v2 0/2] add git-bugreport tool

Having read Dscho's response after already writing this reroll, I think it is a compelling case to rewrite as a C builtin, although I'm worried a little about the best way to continue to call porcelain commands to protect against bitrot.

Regardless, I think the proof of concept in patch 2/2 still deserves review; likely a reimplementation in C would see git-bugreport-config-whitelist generated in a similar way, but as a header instead of a textfile. So I'm still very interested in comments on the direction and the Makefile changes there.

The patch 1/2 changes are primarily based on Stolee and Junio's suggestions; thanks both. There's some rewording of manpage and commit message, as well as fixes when I realized this command did not work as expected from a worktree created with `git worktree add`. I also moved the reflog contents to the very bottom of the output as they're likely harmless, but very verbose; I didn't want the user to stop reading and never examine the shorter and scarier generated output, like the config.

Thanks for thoughts.
