arbitrary filter to contents on check-in/check-out codepath

When the attribute `ident` is set to a path, git replaces
-`$ident$` in the blob object with `$ident:`, followed by
+`$Id$` in the blob object with `$Id:`, followed by
40-character hexadecimal blob object name, followed by a dollar
sign `$` upon checkout. Any byte sequence that begins with
-`$ident:` and ends with `$` in the worktree file is replaced
-with `$ident$` upon check-in.
