byobu doesn't set bash prompt properly

[Arminius Silvanus]

I normally use zsh, but occasionally I switch to bash. In that case, the bashrc in /usr/share/byobu/profiles/bashrc doesn't set my prompt like it should do.

I've done a bit of research on it - byobu's bashrc checks for the environment variable SHELL, which is set to the user's _preferred_ shell, not the currently running shell (see http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap08.html#tag_08). In my case, SHELL points to /usr/bin/zsh, regardless whether I'm running zsh or bash.

The correct way to check if bash is running is to check for the environment variable BASH. I've attached a patch that does just that.
