Without this patch, tools which uses the method SVN.in_working_directory() raises exception which terminates the command:

The description in the ChangeLog should come after the "Reviewed by" line.

The "strategy" you are referring to in git.py was added in <https://trac.webkit.org/changeset/92440/webkit> as  speculative fix for the "svn revision on Windows" problem. That is, it was not added to allow people to run check-webkit-style without a Git checkout. So, I would remove the first sentence of your ChangeLog as it does not justify this change. Please describe that Subversion is considered optional according to the wording on <https://webkit.org/getting-the-code/#checking-out-with-git> and <https://webkit.org/webkit-on-windows/#installing-developer-tools> and explain that this patch makes it so that people with only a Git checkout of WebKit that commit using the commit-queue (or another machine with an SVN checkout) can run check-webkit-style.

[Basuke Suzuki]

Right. Thanks.
