In VisibileUnits.cpp.
Consider startOfWord for the boundary argument LEFT_WORD_IF_ON_BOUNDARY.
If the current position of the caret is at the start of a word, that is considered on the boundary.
The method in this case returns the previous boundary hoping to get the start of the previous word.
However, instead it just returns the end of the previous word, as that is indeed the previous boundary.

Will fix this so that startOfWord does not treat the whitespace between words as boundaries.
I'm not sure yet whether it makes sense to ignore situations where there is more than one character being used as whitespace between words since that seems to be more deliberate.
