Clipboard Errors Cause Command Failure

[synkarius]

• lots of commands, such as the "jump" commands, use the clipboard - failure to get a new value or other clipboard errors cause these commands to fail
• a workaround is to use the copy command on some random thing
• a better solution would involve figuring out when a duplicate value on the clipboard is okay

This was fixed by the freeze workaround I did for @Versatilus. I thought it wasn't because there was another problem with the "fill" command, but that was unrelated. (The keypresses to guarantee nothing is selected before doing the initial backwards-scan caused the cursor to be out of place if the cursor started at the end of the line. That is was 1e5ceea fixes.)
