Thank you for the quick patch.
I've made some small changes and will push the following shortly:
 -- add an entry to NEWS, and mention the affected release (2.19) there
 -- mention the precise commit (in "git describe" format) in the log message
 -- mention the reporter's name in the commit message
 -- correct a comment in the new test file: only grep-2.19 is affected
