fmt:
- Implemented Knuth-Plass optimal linebreaking strategy.
- Added commandline switch -q for "quick" (greedy) split
mode that does not use Knuth-Plass.
- Right now, Knuth-Plass runs about half as fast. It also
uses more memory.
- Updated fmt to use char_width (see below) instead of
assuming each character width is 1.
- Use i64 for demerits instead of int in K-P, since int is
pointer sized and will only be 32 bits on some
architectures.
- incremented version number
- Incorporated improvements suggested by huonw and Arcterus.
- K-P uses indices of linebreaks vector instead of raw
pointers. This gets rid of a lot of allocation of boxes
and improves safety to boot.
- Added a support module for computing displayed widths of unicode
strings based on Markus Kuhn's free implementation at
http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c
- This is in `charwidth.rs`, but this is a temporary measure
until the Char trait implements .width(). I am submitting
a PR for this soon, and the code in charwidth() is what's
generated libcore.
