# git can sometimes get itself infinitely stuck with transient network
# errors or other issues with the remote end. This wraps git in a
# timeout/retry loop and is intended to watch over non-local git
# processes that might hang. GIT_TIMEOUT, if set, is passed directly
# to timeout(1); otherwise the default value of 0 maintains the status
# quo of waiting forever.
# usage: git_timed <git-command>
