This is followup to patch536 that finishes conversion to a new semantics for

2 patches for repository http://darcs.net/screened:

* Move commonly used functions from (Darcs.Command.)WhatsNew to Util
Wed Feb 9 03:34:27 EET 2011 Alexey Levan <exlevan@gmail.com>
* Maybefy lists in patch selection code
Patches 1 and 3 move functions announceFiles and filterExistingFiles
into a new module, Darcs.Commands.Utils to prevent some dependencies
between modules of Darcs.Commands.*
The "maybefy..." patch does a refactor similar to those of patch536 (ie,
Nothing /= Just [], when it comes to filtering on paths).
HEAD + this bundle compiles + shell tests ok, pushing it.
