Log Message: ----------- vimode: Don't use word navigation from Scintilla
Scintilla does different things when using SCI_WORDRIGHT, SCI_WORDLEFT, SCI_WORDRIGHTEND and SCI_WORDLEFTEND than what we want for commands like "w", "b", "W", "B", "e", "E", "ge", "gE". For instance, for
ident1 = id|ent2+ident3;
where | represents the cursor, SCI_WORDRIGHT does
ident1 = ident2+|ident3;
while Vim's "w" does
ident1 = ident2|+ident3;
For this reason we have to reimplement all the word navigation by ourselves to better emulate the behavior of Vim. This patch tries to do that.
