run-tests: suggest to append glob when only path sep does not match
When the line does not match because of \ instead of / (on windows), append
(glob) in the expected output.
This allows to rename test-bla.t.err to test-bla.t for getting a correct
output. This worked for other failures like missing (esc), but not here.
Output example (only +- lines of diff):
Before:
- path/with/local/sep
+ path\\with\\local/sep
Now:
- path/with/local/sep
+ path/with/local/sep (glob)
