[PATCH 0/5] New config option for git-grep to include untracked files

This patch series introduces new config option grep.includeUntracked, which makes the untracked files also searched by default when git-grep(1) is invoked, in addition to searching the tracked files. This is quite handy when someone expects git-grep(1) to mimic grep(1) even better, when it comes to the selection of searched files.

Setting grep.includeUntracked to true in one's git configuration should have no ill effects to various scripts, which presumably shouldn't rely on expensive operations such as git-grep(1).

This series also performs some related cleanups and small improvements, which are extracted into separate patches.
