That is, without leading reference, and where the hierarchy delimiter is
replaced with null characters.

 interimap (0.5) upstream;
 
+ Breaking changes:
+ * interimap: when matching mailbox names against the 'ignore-mailbox'
+   pattern, the hierarchy delimiter is substituted with a null character
+   before hand.  For instance one should now use '^virtual(?:\x00|$)' to
+   exclude the mailbox named 'virtual' as well as its descendants
+   (regardless of the hierarchy delimiter in use).
+
+ Other changes:
  * interimap: the space-speparated list of names and/or patterns in
    'list-mailbox' can now contain C-style escape sequences (backslash
    and hexadecimal escape).
