Subject: Make vim also output a helpful message in some error cases.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=792a51ffb46f0c5d677ba95683ac585e17e70d5f;p=clang

Make vim also output a helpful message in some error cases.

When clang-format encounters a syntax error, it will not format that
line; we're now using the same mechanism we're already using in emacs to
show a helpful error message to the user.
