testcase

Steps to repro:
1. Put the caret in the second (empty) line
2. Press the Left arrow key
- the caret will appear in the middle of the line instead of at the end of it. 
3. Try to place the caret in the second part of the line using the mouse
- that part of the line is not "clickable"

There is also the symmetric case using RTL textarea and LTR Override Character.

OS    Windows XP

This bug contains two issues - First. press the left arrow key from the second line move the caret to the middle of the line instead of the end of it. -- this problem is because webkit lacks of one-to-one correspondence between visual and logical character positions. 

The second issue is unable to place the caret in the RTL text in the first line by using mouse click -- I have created a separated bug 105451 and submit a patch for it.
