record: avoid modifying the matcher passed as a method parameter
No problem observed, but I remember the previous pattern causing problems with
largefiles and/or subrepos. This special matcher was added in 419ac63fe29c, so
directly modifying the `fail` callback was probably an oversight in
44611ad4fbd9.
