commit f0368b130a05e8758a36912c0d652a2a6ae49a43 parent 6587abbdda58cc7c36a118b986a5f06f09d432ae Author: Tim Allen <screwtape@froup.com> Date: Sat, 8 Oct 2016 16:05:21 +1100 Quote meta-characters in the completion pattern. Because we're completing text from the document, we can't assume it's going to be a sensible regex pattern, or glob pattern, let alone both, so we should quote the pattern before we hand it off to helper tools like grep and find.
