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

[Dragan Simic <dsimic@manjaro.org>]

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.
