Feature request: Provide a sane default for certain interactive commands that require an argument

[hupfdule]

I am thinking mainly of the HeaderColumn command here.

When calling this function from a running ov session it requests to enter the Header length:. In the vast majority of cases this will be 1. But ov currently requires that this number is explicitly typed in.

It would be a much better experience if it would default to 1 as this will be appropriate for most cases if no other value is entered.

I don’t explicitly mention HeaderColumn in the title of this bug report as it may apply to other commands, too, but I didn’t check such sane defaults exist for other commands.

Thanks for the issue.

My thinking is that the default is already set in an option or setting, so the HeaderColumn input is used to change the default.

So I don't think a hard-coded value is appropriate. I think a smart guess is appropriate, but I haven't done that yet.
