blame tests: simplify userdiff driver test

avar · gitster · commit f08b4013c3fa · 2021-04-08T12:19:10.000-07:00
Simplify the test added in 9466e38 (blame: enable funcname blaming with userdiff driver, 2020-11-01) to use the --author support recently added in 999cfc4 (test-lib functions: add --author support to test_commit, 2021-01-12). We also did not need the full fortran-external-function content. Let's cut it down to just the important parts. I'm modifying it to demonstrate that the fortran-specific userdiff function is in effect by adding "DO NOT MATCH ..." and "AS THE ..." lines surrounding the "RIGHT" one. This is to check that we're using the userdiff "fortran" driver, as opposed to the default driver which would match on those lines as part of the general heuristic of matching a line that doesn't begin with whitespace. The test had also been leaving behind a .gitattributes file for later tests to possibly trip over, let's clean it up with "test_when_finished".
