Fix the text alignment in the workspace indicator.
Fix the text alignment in the workspace indicator.

We now use 5px padding for the workspace text on both sides. Some
fonts will look off-by-one (e.g. fixed), but that's because X core
fonts have padding. This padding is per-char, varies wildly across
different fonts, and would be a major pain to offset for. Even if
we could take this padding into account, this would probably make
things look even worse for some fonts.
