in reply to tar from another server

The following works for me. (I just have to answer ssh's "password:" prompt on my local keyboard, 'cuz I don't have those nifty ssh keys for the hosts I connect to from home, but that's no problem.)

I decided to make a simple, general-purpose command line utility out of it, because I actually do this sort of transfer often enough myself to make it worthwhile (now I don't have to remember to put in all those parens, etc, on the command line).

update: added more error checking and support for the "-l username" ssh option; also allow for "$src_path" to be empty (i.e., in login user's home directory).
