The wait before clearing a stale shallow.lock looked for a git whose command line began with `git`, so one started as `/usr/bin/git`, which is what a caller that resolved it with `which` runs, was never seen: its lock, once a minute old, would have been cleared under it and a second fetch started against the same shallow file. The path is allowed only ahead of the name, at the start of the command line, so a process that merely names git in an argument, an editor opened on /usr/bin/git from inside the runtime say, is not waited for.
