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

ARTHUR:    Yes!
GUARD #1:  You're using coconuts!

           together.
