For 8 colors, invoke Emacs with "-nw --color".
For 16 colors, try --color=16, and if it doesn't work, try configuring xterm
for 16 colors, then invoke Emacs with -nw.

Yes.  You can use the command "C-x 4 a" to format the log entries, it will
do this automatically if auto-fill is turned on.

This is wrong.

Something like that, yes.

Thanks.
