At the moment calling __fish_prepend_sudo multiple times does not toggle sudo, and also unnecessarily uses the `-c` flag to `commandline` to see if the first token on the commandline is "sudo". This change removes the `-c` switch and also toggles "sudo" on multiple calls to __fish_prepend_sudo, while maintaining the cursor position and while maintaining any spaces between "sudo" and the next token on the commandline.

You can do the same with commandline -C -- (math $cursor - 5)

Ah I can't believe I didn't think of this... any negative result of the math is being counted as an option to commandline that doesn't exist. Nice catch.

At the moment calling __fish_prepend_sudo multiple times does not toggle
sudo, and also unnecessarily uses the
-cflag tocommandlineto see ifthe first token on the commandline is "sudo".
This change removes the
-cswitch and also toggles "sudo" on multiplecalls to __fish_prepend_sudo, while maintaining the cursor position and
while maintaining any spaces between "sudo" and the next token on the
commandline.
The additional logic around the new_cursor position is because the
cursor could be in the "sudo" during the toggle.
