We set the "color.diff" Git configuration directive to "always"
in several tests which exercise the scanning and parsing of
"git log -p" output in order to validate that they still
succeed even with ANSI color code escape sequences in the
Git diff output.
Unfortunately, at the present time, the tests will no longer
succeed as a result of this change, but we intend to resolve
that problem in a subsequent commit.
Currently, our default branch in tests is "master". This is the Git
default, but the Git default will likely change in the future, so it
makes sense to update our testsuite to be explicit about the branch
name. We'll ensure this continues by building against older versions of
Git as well as newer versions.
We use "main" for the new branch name, since that's the proposed value
upstream.
This commit was made entirely by automated means using the following
command:
git grep -l master t | xargs sed -i -e 's/master/main/g'
