-Timeout in milliseconds to use when initializing the runner in temporary
-window. This is intended to provide the runner sufficient time to run the
-initializing commands and then be attached to the Vim window.
-
-This timeout is only relevant if VTR is configured to cd to the git root, or
-run an initial command. These can be set through their respective
-configuration options, |g:VtrGitCdUpOnOpen| and |g:VtrInitialCommand|.
