[Konsole-devel] Extending TerminalInterface

We have facilities for this in Linux and OpenSolaris.  These usually
provide 'good enough' information about what is going on in the
terminal but they are not and will not be completely reliable.

I agree about not wanting to execute 'cd' if there is already
something else in the shell.  Do not class this as a 'data loss' bug -
just say that arbitrary commands entered BY THE USER could be invoked
accidentally.  There are a large number of ways to 'accidentally'
invoke some command which will result in data loss from the shell, the
majority of which have nothing to do with the terminal emulator.

Actually implementing so that it works all of the time is of course
not possible because we don't know how the shell handles input or even
which characters on the screen are output from the shell and which
were entered by the user.  The best we can do is some heuristics that
would tell Dolphin that the user might be at a command prompt and they
may have a command on the line typed which is waiting to be executed.
We cannot pretend that it will always work.

Regards,
Robert.
