Visual select behaves strangely

[lunemec]

Goto pyvim/commands/grammar.py:34
Take cursor to column 41, press v and try to select the line to the beggining with b.
It de-selects the last >!?) characters and when you yank them, they're not there. This is not the first time I noticed this, this happens in other files too.

Another example:
write this text:

in_navigation_mode

Go to beginning and press ve. It selects only to the letter d.

Also the yank is missing the last letter. Use the same word from previous comment and press viw to select visually the word. Then press y. Then create another line and press p. The pasted word is missing last letter. This may be caused by the yank, it sould count the letter below the cursor as being visually selected as well, I think this does not happen.
