Surrounding multiple words

[rightaway]

Using latest version.

aaa bbb ccc ddd

ys2iw' when cursor is on middle c. Should show aaa bbb 'ccc ddd'.

aaa bbb 'ccc' ddd

ys2aw' when cursor is on middle c. Should show aaa bbb 'ccc ddd'.

aaa bbb' ccc ddd'

ys2iw' when cursor is on middle b. Should show aaa 'bbb ccc' ddd.

aaa 'bbb' ccc ddd

ys2aw' when cursor is on middle b. This is as expected.

aaa 'bbb ccc' ddd

Try these commands using v instead of ys (and, of course, omit the '). This is just how "inner" and "a" text objects with with counts.

Though it seems maybe surround.vim is detecting "unwanted" space and trimming it, but perhaps missing the edge case. Whitespace is trimmed when there is whitespace at the end of the target, but not when it's only at the beginning?

To demonstrate, using the same text, compare ysaw' with the cursor on c vs on d.

The edge case in question is that Vim will normally include trailing whitespace for the aw object unless it's the last word on the line, in which case it will include leading whitespace.

Feel free to dig deeper on that edge case, but it sounds like the core problem is a non-issue.
