* assistant, watcher: .gitignore files and other git ignores are now
honored, when git 1.8.4 or newer is installed.
(Thanks, Adam Spiers, for getting the necessary support into git for this.)
* importfeed: Ignores transient problems with feeds. Only exits nonzero
when a feed has repeatedly had a problems for at least 1 day.
* importfeed: Fix handling of dots in extensions.
* Windows: Added support for encrypted special remotes.

{- exception handling in the git-annex monad
|
|
-
|
|
- Note that when an Annex action fails and the exception is handled
|
|
- by these functions, any changes the action has made to the
|
|
- AnnexState are retained. This works because the Annex monad
|
|
- internally stores the AnnexState in a MVar.
