rethrow ExitStatus exceptions

Several git-annex commands want to exit right away, but that's an
exception, which is caught due to 39fbaa0682.
So, re-throw it.

 This is a reversion due to [[!commit 39fbaa0682198ba0fd8aa437b8382b13fb71e66f]]
 that breaks any part of a git-annex command that uses exitWith since that
 is actually implemented as an exception which now gets caught.

+(Seems that when I tried the test suite after that commit I stopped reading
+at the "All 293 tests passed" because it does always go on to fail.)
