When moving from a line to a shorter one, we now make sure the cursor don't overflow it by moving it to the last character when necessary.
Display backtrackes on failing tests.

Fixes

The hash of the last saved document is always updated when the save is successful, saving us from having to run :q! on a freshly saved doc.

Features

Trailing spaces are now removed on save. Thanks @ilmanzo !
New NORMAL mode command: J, joins the current line with the previoue one

The welcome message is automatically hidden as soon as we start writing anything in an empty buffer
