Originated from #53.
As far as I can see there is no trivial way to do this, so I went the easiest way and forced developers implementing listeners to be cautious and do be aware about might-be-clashing manipulations of text and/or attributes.
7e39198 tinily improved removing of autocompleted text leaving preceding character (which is probably a space AFAIK). (e.g "Hello @SD10" becomes "Hello " instead of "Hello")
