I have two suggestions and one comment. Before that, I would like to
highlight the importance of tools like that to help with repetitive
tedious work, it is great to have this script.

I appreciate the correspondence between job name and expectation file
names.

Suggestion: it is not managing empty lines or comments. By now, there
aren't, but they could be found.

Suggestion: Sometimes tests fails with different status ("Fail" to
"Crash" for example) and the expectations should be updated with the
newer status.
