Problem: b:match_words groups "{" with the if/for/while/switch keywords
and "}" with "break" which breaks % matching on braces
Solution: Drop the brace and bracket groups, matchit appends
'matchpairs' by itself (Matthias Bruns).
matchit counts every alternative in a group instead of pairing the
alternatives with each other. Listing `{` alongside the if, for,
while, switch, struct and class keywords therefore makes a line such
as `for (...) {` count as two openers, and listing `break` alongside
`}` lets a brace pair with a break statement. As a result % on the
opening brace of a function does not move at all, and % on
`switch (x) {` jumps to `break;` instead of the closing brace.
Braces and brackets do not need to be listed: matchit appends
'matchpairs' to b:match_words by itself. Drop them and leave the
preprocessor group unchanged.
