wxRichTextCtrl: Not able to move up to empty first line

[walderich]

I am not able to use the <up> key to move to the first line in a wxRichTextCtrl, when it is empty.

I tested this using the richtext sample application as reference. To reproduce the problem, do the following steps:

1. Delete all text inside the control
2. Press <enter> key once
3. Press <up> key for moving to the first line again

What I can see then is, that the cursor still is on the second line. It is not possible to move to the first line with the <up> key. Using the mouse is also not working correctly. When clicking on the first line, the cursor is moved to the start of the second line.

Using other keys, like <backspace> or <left> is still working, as is clicking before the first line with the mouse. This only happens, when the first line is empty.

I could reproduce this behaviour under wxMSW (MinGW) as well as wxGTK with version 2.9.4.
