in the alef version of acme i made a change so that the window id was
set in $acmewin so that shell scripts that wished to could operate on
the window they were executed from.

i did that largely so that i could implement aget and aput commands
which got or put some text into the selection of the current window so
you could do

	aget|fmt|aput

however since the '|' functionality has been implemented that's not so
useful.

one feature i would find useful: an environment variable giving the
filename of the current window (from the tag).  to save valuable space
in tags, it should probably be a single letter, maybe $% ?

cp $% $%.old
Edit ,>diff $% /fd/0
