I've just rebuilt from CVS and tried tabs, with `xemacs -q'.
The colors are now fine. However, I'm not sure if they work right.
Take this: `xemacs -q', the tab says "*scratch*". Now I press
`C-x b fweifohwefweioh RET', and scratch disappears from the gutter,
replaced by "fweifohwefweioh". Shouldn't they both be there?
