[nvi-iconv]Weekly status report

[Zhihao Yuan]

To whom may concerned:

Before talking about the coding stuff, let me explain something about
my schedule. According to my proposal, I should start this project at
5/16. But I was struggling with the paper works to get my CPT (working
permission) during that week, so I will just move my schedule to the
regular GSoC time.

For the first week, I planed to read and clean up the nvi-1.79 code. I
moved the code from contrib to usr.bin since I'm forking the project
for FreeBSD. I updated the autotools, and added a HAVE_TERM_H test to
solve the <term.h> problem (finally, according the the commit
history). Other misc changes can be seen from the svn log.

One of the problems I met so far is the CHAR_T usage in nvi. In nvi,
it's a typedef to unsigned char, which is used to represent the
command (to be able to map them in arrays). But in nvi-1.81, CHAR_T
(wchar_t) is used to represent the input text. Before deciding whether
to use wchar_t in this project, I hope I can trace the char type usage
more deeply and can hopefully get rid of the related warnings.
