tests: fix regex in test-subrepo-git.t to match entire string Due to a bug in the test runner (fixed by the next commit), the regex used for matching lines like " foobar | 2 +-" stoppped at the "|" and the test passed even though the rest of the line did not match. The test seems to have been supposed to match "|" and "+" literally on those lines, so this changes the regex to escape those characters. It also changes a "\s*" to "\s+" since I think we'll always include a space after the "|" in the diffstat output. Differential Revision: https://phab.mercurial-scm.org/D1545
