@gridGutterWidth in customize not working properly

[HermesGit]

In "Grid system" - under :
http://twitter.github.com/bootstrap/customize.html#variables

Set those parameters like this :
@gridGutterWidth: 0px
@gridGutterWidth1200: 0px
@gridGutterWidth768: 0px

Try to extend from a mobile size to 1800+, in some case it's perfectly working - in some the spanX margin-left is still there.

The code doesn't have to be "special" to see this bug, it's just a basic row-fluid with some spanX inside.

For now we'll punt this—v3 is bringing a new grid.
