#79 Window title duplication

[Wey]

RoxTerm has been my favourite terminal emulator for some time now. I noticed a small bug regarding the window title. In the preferences menu, my window title is set to "%s Terminal". When opening a new window, the initial tab is named "ROXTerm" and the window "ROXTerm Terminal". When opening and closing e. g. vim, which sets its own title, the tab title becomes "ROXTerm Terminal", and the window title "ROXterm Terminal Terminal".
So when i use vim to repeatedly edit a set of files, the tab and window titles escalate to very long concatenations of "Terminal"s.

I'm not familiar with the roxterm code base, but my take is, that when an sub-application terminates, the tab title is restored to the previous window title instead of the previous tab title.

Ah, I had seen something like this before but couldn't reproduce it. Now I know how, but I don't think I can fix it. There are two things you can do to avoid the problem. One is to have bash set the terminal title whenever it prints a prompt. For example including the following in PS1 sets the title to the current directory (I think [\e]0; is the start sequence and \a] the end sequence) :

[\e]0;\w\a]

Alternatively set the window and tab title templates to %s on its own.

AFAICT the problem is because roxterm and gnome-terminal (in which I can reproduce a similar problem) allow the actual window title to be set to something different from the terminal title set by the program running in the terminal, and when the concept of a terminal title was invented nobody foresaw that the window title might not always exactly correspond to the terminal title, so there's no way to read a terminal title except by assuming the window title is the same and reading that.
