instead of individual components; initmodule3() now has doc string
argument as well

(a) support import NAME.NAME...NAME;
(b) support doc strings in modules, classes and function definitions

	use new instancebinop interface

	instancebinop, to support things like Rational * float; added
	documentation strings to classes and methods

	contains a pointer to the struct methodlist (which must be
	static); added attributes __name__, __doc__ and __self__

constant in code object if it is a string, else None

lib.tex: add libimp; remove bogus warning about lineii.
libmath.tex: document hypot().
libmd5.tex: rename md5.md5() to md5.new().
libposix.tex: document chown().
libposixfile.tex: openfile() instead of fileopen().
libsocket.tex: document gethostbyaddr().
libtypes.tex: add footnote explaining why readline() keeps the newline.
ref3.tex: correct typos, add back*quotes to index.
ref4.tex: don't use \verb inside footnote.
ref5.tex: explain repr() and str() and add them + back*quotes to index.
ref6.tex: correct typo, don't use \verb in footnote.
ref7.tex: don't use \verb in footnote.

bltinmodule.c: fixed coerce() nightmare in ternary pow().
modsupport.c (initmodule2): pass METH_FREENAME flag to newmethodobject().
pythonrun.c: move flushline() into and around print_error().

Setup.in: clarified Tk comments somewhat.
structmodule.c: use memcpy() instead of double precision assignment.

floatobject.c: fix hash().
methodobject.c: support METH_FREENAME flag bit.

object.h: made sizes and refcnts signed ints.
stringobject.h: make getstrsize() signed int.
methodobject.h: add METH_VARARGS and METH_FREENAME flag bit definitions.

Makefile.in: run config.status in "make recheck".
configure.in: add test for hypot().
config.h.in, configure: since configure.in changed.
rest: the usual boring stuff.

	lookmapping() for empty dictionary

Note addition of gethostbyaddr() and improved repr() for sockets,
renaming of md5.md5() to md5.new(), and fixing of leaks in threads.
