Re: Patches for --vnlog support

[Dima Kogan]

Alright. Tell me what you want.

Another way you can clarify the logic, and to make it amenable to
supporting future formats is to be more clear about why any given
if(vnlog) is there. Currently --vnlog does several things:

- -W
- -C
- -H
- trailing comments ignored
- numerical column references disabled
- column labels come from the first # comment

I think that's it? That's most of it, at least. The first 3 features set
variables in the code, and there are if() statements for those features.
We can do that for the other features too. For instance we can have a
variable "ignore_trailing_comments", and the relevant if() statement can
act on that, and not the "vnlog" variable. Then future formats that want
that behavior can set that variable, instead of introducing any more
if() statements.
