announcing es-0.7

[Chris Siebenmann <cks>]

[posted for Paul Haahr, since I controlled ftp timing :)]
ok, i've been talking about this for a few days, but here it is.
some of the complaints from the list have been addressed, others
are pending.  other features from the TODO list are now done.  see
the file CHANGES for details.  the major still missing features:

	- redefinition of read-eval-print loop
	- /dev/fd operations (i.e., >{} and <{})
	- redirection of primitives w/o forking
	- exporting of recursive structures

this release fixes many bugs, and should be installed for that
reason alone.  highlights of new features:

	- heredocs are implemented
	- ~ and ~user are supported by the globber
	- the vars command corresponds to rc's whatis w/o arguments
	- var corresponds to rc's whatis for variables
	- the path searching mechanism can be redefined w/%whatis
	  (but be careful---see the example)

in addition, i think it's much more portable w.r.t. header files.

as usual, please send comments either to the list or directly to
Byron and me.
