This sample script does not work properly when use visual-block-mode with '$'.
How to reproduce:
(0) Prepare test.txt containing the following.
a a
b b b b
cc
(1) Copy to ~/.vimrc above sample script.
(2) Open test.txt
(3) Input below command.
<C-V>G$
(4) Press <F4>
Expected behavior:
- Display '5' on command line.
Actual behavior:
- Display '3'.
I think that we should use 'gv' in this case.
Attached a patch.
PS
Is it necessary condition "elseif a:type == 'block'" ?
Help says unnecessary. (Following excerpt)
doc> Although "block" would rarely appear, since it can
doc> only result from Visual mode where "g@" is not useful.
Thanks.
