Re: Multibyte support for sort, uniq, join, tr, cut, paste, expand, unexpand, fmt, fold, and pr

[Eric Fischer]

Thanks for the list of things to do. Most of them are done now:

  * I have added documentation for what has changed in each program.

  * The new files have copyright headers now.

  * "make check" succeeds.

  * "make syntax-check" succeeds, except for a complaint about strftime in
code that I have not touched (strftime_check), and a list of utility
functions that it thinks should have static scope even though they are used
from multiple programs (tight_scope).

  * "make coverage" has some mysterious errors, mostly in programs that I
have not touched, and the coverage report doesn't include most of the files
that I have touched. So I don't know what to do with that.

I haven't squashed the commits because there seems to be some question
about whether that is a good idea.

I look forward to your further review of the changes.

Eric
