   * Fix #3189: add docs to findExecutable
 }}}

 d'oh, I got the bug number wrong in the patch.  Oh well.

 The docs for `findExceutable` now say:

 {{{
 -- | Given an executable file name, searches for such file in the
 -- directories listed in system PATH. The returned value is the path
 -- to the found executable or Nothing if an executable with the given
 -- name was not found. For example (findExecutable \"ghc\") gives you
 -- the path to GHC.
 --
 -- The path returned by 'findExecutable' corresponds to the
 -- program that would be executed by 'System.Process.createProcess'
 -- when passed the same string (as a RawCommand, not a ShellCommand).
 --
 -- On Windows, 'findExecutable' calls the Win32 function 'SearchPath',
 -- which may search other places before checking the directories in
 -- @PATH at .  Where it actually searches depends on registry settings,
 -- but notably includes the directory containing the current
 -- executable. See
 -- <http://msdn.microsoft.com/en-us/library/aa365527.aspx> for more
 -- details.
