Ok i now look if the caret is at the end of a word, and if so, i do not show it as error. This is the closes i can think of without complicated logic (store with a decay time if the user modifies a word and ignore it for some time before it is checked or similar...)... I do not want to invest more time in this...
[edit:] I also committed this to trunk... I do not want to switch branches with svn... If this should be in release, please cherry pick...
