Visual mode: increment letters of the alphabet and roman numerals clash

[kiryph]

Consider I have an alphabetically enumerated list:

a)
b)
c)

I'd like to increment them in visual mode. I get following result:

b)
c)
ci)

How could this be resolved?

• no roman numerals incrementing in visual mode
• same 'type' incrementing when applying to several lines.

I know roman numerals can be disabled by :SpeedDatingFormat! but I would expect a consistent default behaviour of speeddating itself.

In hindsight, I think a better visual mode behavior would be to clobber the second row onward with additional increments of the first, sidestepping this entirely. This already happens when the rows are blank so forcing it to happen all the time is probably tenable. Please do investigate.

Note: current Vim do provide <C-A> <C-X> functionality for visual mode plus adding the g<C-A> function

@chrisbra: I didn't follow your comment. g function? You mean like :g//? I don't see how I'd use that in this situation. Please elaborate?

@tpope: this problem exists even outside of visual mode. Today I hit ctrl-a on this line:

id: 3

I expected:

id: 4

but I got:

dii: 3
