New Revision: 171480

URL: http://llvm.org/viewvc/llvm-project?rev=171480&view=rev
Log:
Handle segfaults in clang-format vim-integration.

A segfault used to clear the entire buffer. With this change, a message
to report a bug is displayed instead.

This should solve most cases similar to llvm.org/PR14774.
