tramp (2.1.20); learn how to work with Android 2.2 via DroidSSHd

[Ivan Zakharyaschev]

Hello!

I'm reporting a possible enhancement in TRAMP, so that no error
happens when we try to connect to Android, and so that TRAMP can work
with Android over SSH.

Now it breaks when it tries to call "env". It could detect this kind
of system on the remote end, and work around the missing commands.

More details about my case are published here:
https://bugs.launchpad.net/emacs/+bug/1041474

Or a special method for Android over SSH could be devised, perhaps
based on https://github.com/juergenhoetzel/tramp-adb , because I
suppose the restrictions of the set of available commands are similar
-- whether we connect via adb or ssh.

Best regards,
