Support incrementing/decrementing the number below the cursor

Browse Source 
Vim supports incrementing & decrementing the number below the cursor (or
after it) via Ctrl-a and Ctrl-x, respectively. Given fish's Vi mode
support, it makes sense to provide similar functionality when working on
the command line, to provide a more natural environment for Vim users.
With this change we add the necessary functionality.

Closes: #8320
Closes #11570
