Comment #1 on issue 677 by spielmann.robert: Helper methods accidentally
exposed as keywords in Dialogs library
http://code.google.com/p/robotframework/issues/detail?id=677
I debugged this a little, and it is caused by the following:
* In r3638, Janne fixed something about get_version, so now there's a "from
robot.version import get_version" in line 29 of Dialogs.py
* In r4103, a fix for issue 641 (timeouts on Win+Python) was made,
adding "from threading import currentThread" in line 86 of Dialogs.py
So, _BaseTestLibrary._get_handler_names, which does a dir(libcode), will
produce "get_version" and "currentThread" as additional values, and those
result in the broken docs.
