Recoding of {git,cg}-log output

First: a little "why": having /usr/bin/vim as PAGER allows to enter
UTF-8 commit messages quite easily, the problem is when git-log (or
cg-log) is run in terminal that's not UTF-8. In my case: terminal is
ISO-8859-2 and:

nelchael@nelchael ~$ cat ~/.vimrc | grep gitci
au BufRead /tmp/gitci* setlocal textwidth=75 fileencoding=utf-8
encoding=utf-8 fileencodings=utf-8,default

So... having {git,cg}-log recode the log entires when displaying is
quite useful. Two patches attached:

 a. git-log-recode.patch - uses iconv to recode the log output to
GIT_LOG_RECODE encoding
 b. cg-log-recode.patch - the same, but for cogito

With this patches it's possible to write UTF-8 commit messages and see
them ok in non-UTF-8 terminal in log by having GIT_LOG_RECODE=iso-8859-2.

Comments?
