In Tramp, it is the default case that the local shell is different from
the remote shell. The local shell could be even w32's cmd.exe. Tramp
handles this.

You know, that Tramp supports older Emacsen as well as XEmacs 21.4+?

And `tramp-shell-quote-argument' binds also `system-type' in order to
get a proper result for the remote bournish shell. Admitted, this is not
a documented way to do this ...

This is an obsolete comment, older than 10+ years. It should have been
removed long ago; thanks for the heads up.

You are invited to support me as co-maintainer of Tramp. Seriously.
Writing compatibility code is one of the major tasks.
