[PATCH v3 3/9] emacs: Helper for reporting search parsing errors

Subject: [PATCH v3 3/9] emacs: Helper for reporting search parsing errors

This removes the last bit of direct output from the parsing function.
With the parser now responsible solely for parsing, we can swap it out
for another parser.
