"omap f <Plug>Sneak_f" does not include last char in buffer (using "co")

[blueyed]

Given a minimal vimrc:

let &runtimepath .= ','.fnamemodify(expand('<sfile>'), ':h')
omap f <Plug>Sneak_f

cfl in a buffer that contains only one like "eval" will result in l being left (and not changed/removed).
This appears to be related for when it is at the end of the buffer, i.e. a newline after it will remove the "l" as expected.

I wonder if #181 fixes this.

Nope..

Yep, operators won't work properly if the target area extends to the very last column in the buffer, because we cannot "nudge" the cursor beyond the last column (to compensate the default "exclusive" interpretation of the motion). There are two solutions: 1. We can just tell the user to use the 'v' modifier, forcing inclusiveness (:h o_v) 2. We could set virtualedit temporarily to onemore, move the cursor beyond the last column, and then revert virtualedit with an autocommand after the function has finished. Do we need to bother with this edge case?

good idea! not ideal because it changes the :verbose set virtualedit? history, but we could be smart about it and only do this hack when this edge case is detected.
