Is there a way to set the TERM variable?

It seems that Sakura, like almost every other terminal emulator,
lacks a way to set the TERM variable. It defaults to "xterm", but
I would like it to be something like xterm-256color, as some
programs (like Vim) rely on this information.

The method of setting it in a shell init script
(.bashrc/.profile/.zshrc/whatever) is wrong, as the shell does not
know about the terminal. It is the terminal that should set the
variable.

As far as I know only a few terminals do this: rxvt-unicode-256color,
stterm (from suckless) an maybe a few others.

Would it be possible to add this feature to Sakura?

Thanks!
