Unable to move last line with shortcuts if it is empty

Environment: Reproduced in mousepad 0.5.1git-110221c (shown on about screen) compiled locally

Steps to reproduce

• open mousepad
• fill some lines than can be told apart
• add one empty line at the end

Expected behavior

Pressing Alt+Up/Down moves the current line.

Observed behavior

If the last line is empty and the cursor is placed there, pressing Alt+Up will move the cursor up one line without affecting the document. If the cursor is placed in a line that contains text and is right above the empty last line, pressing Alt+Down does not trigger any reaction.

Empty lines can be moved or passed while moving other lines anywhere else in the document.

 

I can imagine that this is probably some annoying edge case that requires extra logic to specifically treat this situation. I think it would be perfectly fine to leave this as is, just thought i would report it as unexpected behavior.
