	* library/http/http.tcl: Backported a fix for reading HTTP-like protocols
	that used to work and were broken with http 2.7. Now http 2.7.2

2008-10-23  Don Porter	<dgp@users.sourceforge.net>

	* generic/tcl.h:	Bump version number to 8.5.6b1 to distinguish
	* library/init.tcl:	CVS development snapshots from the 8.5.5 and
	* unix/configure.in:	8.5.6 releases.
	* unix/tcl.spec:
	* win/configure.in:

# http.tcl --
#
#	Client-side HTTP for GET, POST, and HEAD commands. These routines can
#	be used in untrusted code that uses the Safesock security policy. These
#	procedures use a callback interface to avoid using vwait, which is not
#	defined in the safe base.
