Aaand here it is:

1. Enter the Emacs checkout, pull the latest commit, 'make' to make sure 
the new change is preloaded.

2. emacs -Q.

3. M-x project-find-regexp, enter 'turn-on-eldoc-mode'.

4. See the user error about status 1, and the message containing four 
grep hits. Doing this search with Ag confirms the same set of hits (with 
normal exit status).

Could someone please explain why find-grep exits with status 1 here?

It's not the command line invocation, or else we'd be getting this exit 
status for other similar inputs.
