[vim/vim] v_CTRL-A/X not incrementing some numbers when selection ends in an empty line (#2387)

[Alex]

Selecting several numbers followed by an empty line and then using CTRL-A/X can result in only some of them being incremented/decremented. v_g_CTRL-A/X shows similar behaviour.

Input to reproduce:
10i0<CR><Esc>vgg<C-A>

Result:

1
1
1
1
1
1
1
0
0
0

I've reproduced this on MSYS2 on Windows using version 8.0.1305 and in gvim on Windows using version 8.0.586, both with vim -N -u NONE.

Thanks for the quick patch! I don't currently have a vim build set up, but if it would help, I could set one up and try it out when I have some time, hopefully within the next week or so.
