Re: [PATCH] t2028: tighten grep expression to make "move worktree" test more robust

> Following a rename of worktree "source" to "destination", the "move
> worktree" test uses grep to verify that the output of "git worktree list
> --porcelain" does not contain "source" (and does contain "destination").
> Unfortunately, the grep expression is too loose and can match
> unexpectedly. For example, if component of the test trash directory path
> matches "source" (e.g. "/home/me/sources/git/t/trash*"), then the test
> will be fooled into thinking that "source" still exists. Tighten the
> expression to avoid such accidental matches.

> While at it, drop an unused variable ("toplevel") from the test and
> tighten a similarly too-loose expression in a related test.
