Problem: [security]: arbitrary Ex command execution during C
omni-completion (Threonine)
Solution: Match tags typeref literally to block Ex command injection
(Yasuhiro Matsumoto).
Escaping only "/" and "\" left the typeref able to break out of the
:vimgrep pattern without a "/": an unclosed "[" makes vimgrep's pattern
skipping fail, and the parser then treats a following "|" as a command
separator, so the tag value runs as Ex commands during C omni-completion.
Match the field literally with \V so no regex metacharacter can affect
pattern parsing.
