Subject: [PATCH v3 10/35] blame tests: simplify userdiff driver test

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Wed, 24 Feb 2021 20:51:04 +0100

Simplify the test added in 9466e3809d (blame: enable funcname blaming
with userdiff driver, 2020-11-01) to use the --author support recently
added in 999cfc4f45 (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, and further modify 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.

The test also left behind a .gitattributes files, let's clean it up
with "test_when_finished".
