+Subject: [PATCH] Revert "Fix grepdiff test"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit a6538753a51db973a05c9034ed78f2dd946453db.
+
+There's no need for an escape here, because POSIX regexes don't treat
+'+' specially if it's at the start of the experssion.  musl rejects
+the version with the backslash.
+
+I'm still not clear why this change was made in the first place, but
+reverting it seems to make the test pass on both glibc and musl…
