Vim command to increment number digit ONLY at cursor position in a longer number string?
===

I have a few instances where I want to do the following

In file:

    1234

With the cursor at the 1st digit, I want to use Ctrl-A to increment the digit so that I get

    2234

instead of

    1235

Are there intrinsic vim commands to do this?

Otherwise, should I set up a quick script:

1. Surround digit with leading and trailing space
2. Ctrl-A to increment
3. Delete leading and trailing space

Like so, and then map to a key?
