Patch 7.3.650

Problem:    Completion after ":help \{-" gives an error message and messes up

	    the command line.

Solution:   Cancel the tag search if the pattern can't be compiled. (Yasuhiro

	    Matsumoto)

Files:	    src/tag.c

GUARD #1:  What, ridden on a horse?

ARTHUR:    Yes!

GUARD #1:  You're using coconuts!

ARTHUR:    What?

           together.
