[tex-live] another final TL'11 build

[Karl Berry]

I've updated the TL'11 pretest area with another (hopefully final, as
before) build.  The changes are:

1. New (e)pTeX for Windows only, to fix an encoding/fmt generation issue
(thanks Akira).

2. Quoting fix to be able to install from a source directory containing
spaces on Windows (thanks Tomek).

Barring any more drop-dead issues coming to light in the next day or
two, this will be it for the DVD.
