That basically would be the idea. Perhaps something like this on top of
a9e6436 (grep --no-index: don't use git standard exclusions, 2011-09-15).

Subject: [PATCH 1/2] grep: teach --untracked and --exclude options
In a working tree of a git managed repository, "grep --untracked" would
find the specified patterns from files in untracked files in addition to
its usual behaviour of finding them in the tracked files.
By default, when working with "--no-index" option, "grep" does not pay
attention to .gitignore mechanism. "grep --no-index --exclude" can be
used to tell the command to use .gitignore and stop reporting hits from
files that would be ignored. Also, when working without "--no-index",
"grep" honors .gitignore mechanism, and "grep --no-exclude" can be used
to tell the command to include hits from files that are ignored.
