If an action that requires the keyboard to be grabbed (e.g., launching dmenu),
it is a race when submapping the action as to whether the action will have
access to the keyboard or not. To fix this, the keyboard should be ungrabbed
before executing the action.
This better expresses the idea that the argument to alwaysTrue is just there to
select an instance. Another option could be to do use a fundep, which seems to
be compatible with the two instances so far.
class Predicate p w | p -> w
Now the number of runs each can be set, and the failures and successes are
summarized in the same way as the core Properties.hs. There is some duplicated
code which could be avoided by modifying Properties.hs.
Daniel's change which broke -Wall (adding an import for haddock only) was
somehow removed. Instead we can just modify the sample code to add the import.
Based on Adam Vogts recommendation on the mailing list. I had to give explicit
type signatures to get rid of warnings, but nearly verbatim to his version.
LayoutBuilderP is similar to LayoutBuilder (and is based on it), but LayoutBuilderP places windows matching given X.U.WindowProperties.Property (or any other predicate) into one rectangle, instead of fixed number of windows.
Somewhere between my creating the original version of this script and
adding it to the tree, a backslash got lost. It appears to have been
lost in the version I put on the wiki, so I suspect a copy-paste
problem at that point.
Spotted by arlinius in #xmonad, and this only shows up for xinerama setups.
Using an algorithm that scales better with number of workspaces would probably
be shorter too (visiting them in turn, rather than doing random access), but
probably not worth the effort.

dylan did not supply a patch and his version doesn't match the declared type signature;
since I don't want to break every `safeSpawn` user, I tossed a `>> return ()` in to make
the type right, although I'm troubled at removing the exception functions.
It is possible that this atom should be defined in the X11 library, but fix the
build of contrib for now. In any case, this would have to wait for a change and
release of the X11 binding.

* Remove accidental atom_WM_TAKE_FOCUS from H.ICCCMFocus
The XMonad module exports this already

This patch adds support for calling countScreens in arbitrary places. Prior to
this patch one would end up with an open display for each call of the
countScreens function with would eventually mess up X. This patch ensures that
the display that is no longer needed is closed after the operation and thus
using the function without side effects.
