Positional parameters with the bashdb debugger integration

[jansorg]

Currently the command line is similar to bash /path/to/bashdb /path/to/script.bash. This changes the values of $0 and other positional parameters. If possible, these values shouldn't change in the debugger.

It might be possible to use bashdb's set0 command, but this needs to be investigated.
