Return to 166 CVS log

Up to [Development] / xfs-cmds / xfstests

Fix pathname filter issue.

If the path to the file being bmap'd has a [0-9] in it,
the output filter matches it and we get golden output
failure. Be more specific on the match.
Merge of master-melb:xfs-cmds:31170a by kenmcd.

  Be more specific when trying to match extent output lines.
