convert: config option for git rename limit
By default, Git applies rename and copy detection to 400 files. The
diff.renamelimit config option and -l argument to diff commands can
override this.
As part of converting some repositories in the wild, I was hitting
the default limit. Unfortunately, the warnings that Git prints in this
scenario are swallowed because the process running functionality in
common.py redirects stderr to /dev/null by default. This seems like
a bug, but a bug for another day.
This commit establishes a config option to send the rename limit
through to `git diff-tree`. The added tests demonstrate a too-low
rename limit doesn't result in copy metadata being recorded.
