I have a problem with my colorscheme in vim:

The line numbers are too close to the code. How I can increase the width of the line numbers' right margin?

Looking at the code, it turns to be impossible (without patching the vim, obviously): vim always formats the line numbers to take up the whole available width, leaving just a single space afterwards (the "%*ld " format specifier in the code makes sure of that).

This bothered me, too; I hate having text crammed up against a block of solid color. It makes me claustrophobic.
Here's what I did as a workaround (in MacVim, but I expect the same technique will work elsewhere):
In your preferred colorscheme, set the background color of the line-number column to be the same as the background color for normal text, and the line-number foreground color to something low-contrast and unobtrusive (so it doesn't look like it's part of your normal text). I use white-on-black for normal text, and dark-grey-on-black for the line numbers:
hi LineNr guifg=#505050 guibg=Black
hi Normal guifg=White guibg=Black
Admittedly, this doesn't fix the problem so much as hide it, but it's worked well for me.

You can add the following line in your "~/.vimrc":
set nuw=6
Where "6" specfies the width of the column in terms of number of characters. Replace with a smaller or large number as needed. Only works with more recent (>=7?) versions of Vim, I think.
