SZEDER Gábor beb6ee7163 completion: extract repository discovery from __gitdir() ... To prepare for caching the path to the repository in the following commit, extract the repository discovering part of __gitdir() into the __git_find_repo_path() helper function, which stores the found path in the $__git_repo_path variable instead of printing it. Make __gitdir() a wrapper around this new function. Declare $__git_repo_path local in the toplevel completion functions __git_main() and __gitk_main() to ensure that it never leaks into the environment and influences subsequent completions (though this isn't necessary right now, as __gitdir() is still only executed in subshells, but will matter for the following commit). Adjust tests checking __gitdir() or any other completion function calling __gitdir() to perform those checks in a subshell to prevent $__git_repo_path from leaking into the test environment. Otherwise leave the tests unchanged to demonstrate that this change doesn't alter __gitdir()'s behavior.
