Description: The test 'syntax_errors_in_.mtn-ignore' from the monotone
 test suite contains a .mtn-ignore file which contains a number of
 regular expressions. Some of these are intended to match and fail to
 match the names of files created by the test harness. The rest have
 invalid syntax and should be ignored.
  .
 One regex, '(?<=\C)' is presumably intended to be invalid, but with
 the most recent version of pcre3 matches most files and therefore
 causes the test to fail. In fact, it appears to be a valid regex that
 performs a positive look behind to match a single data unit (usually a
 byte, even in UTF mode). This patch removes the problematic regex until
 the issue can be addressed upstream.
