Subject: worktree: add relative cli/config options to `move` command
X-Git-Tag: v2.48.0-rc0~11^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=298d2917e26520791b47ba5d38c1866e21894cc7;p=thirdparty%2Fgit.git

worktree: add relative cli/config options to `move` command

This teaches the `worktree move` command to respect the
`--[no-]relative-paths` CLI option and `worktree.useRelativePaths`
config setting. If an existing worktree is moved with `--relative-paths`
the new path will be relative (and visa-versa).
