Show first indentation level

[padde]

When you use set listchars=tab:│\ in order to show tabs along indentLine, the result is not very pretty. This is because indentLine does not show the first indentation level:

In general, i think it is good not to show the first indentation level, but listchars doesn't seem to provide this option. (Please correct me if i'm wrong). So i'd like to either be able to display the first indentation level with spaces, or to not display the first indentation level with tabs.

I can think of a few possibilities to address this issue:

1. Provide an option to set if the first indent level is shown, e.g. g:indentLine_showFirstIndentLevel, default 0
2. Provide an option to set the minimum indent level, e.g. g:indentLine_minimumIndentLevel, default 1
3. Extend indentLines to show tabs, too. I admit this is my favourite option, as all indentation visualization would then be handled in one place, and there would be no need for showing the fist indentation level at all. Could be combined with (1) or (2)

Please ignore the first two commits, i accidentally commited them, then amended and force pushed again. Sorry

Thanks for merging! Should we close this for now?

How do you feel about showing Tabs?

Actually, I don't think it's a good habit to indent code with both tabs and spaces. So I set 'expandtab' in vim. And I don't plan to support showing Tabs. If someone would, he can do it by himself.

I think mixing both is a horrible thing to do, but i have to look at legacy code quite often, which is indented this way.

Anyway, at the time of this writing, my fingers already type gg=G automatically when they see poorly formatted code :-)

Cheers!
