	lsh_string_bubblebabble.

	* src/lsh.c (do_lsh_lookup): Rearranged the unauthenticated key

	bubblebabble a string.

	* src/format.h (lsh_string_bubblebabble): New function to
	bubblebabble a string.

	lsh_string_bubblebabble.

	* src/lsh.c (do_lsh_lookup): Output the fingerprint of the remote

	lowercase letters 'l' and 'b' for the endianness indicator.

	option. 

2002-03-26  Niels Mller  <nisse@cuckoo.hack.org>

	* src/lsh-authorize: Don't use &>-redirects, as /bin/sh doesn't
	understand that. Noticed by Timshell Knoll.

2002-03-25  Niels Mller  <nisse@cuckoo.hack.org>

	* src/lsh-execuv.c: Deleted utmp stuff, this is not the right
	place for that.

2002-03-26  Pontus Skld  <pont@soua.net>

	* configure.in: If with_scheme is absolute, don't AC_PATH_PROG for
	it but just use it directly.

	subsystem help text if PTY-support is enabled.
	(client_argp_parser): Turn of pty-request if there is a subsystem

	the last command in the user's startup files ended with nonzero
	exit status.

	* src/testsuite/lsh-5-test: Likewise.
	* src/testsuite/lsh-6-test: Likewise.
	
	* src/testsuite/lshg-1-test: grep -q changed to redirection to
	/dev/null.

2002-03-20  Niels Mller  <nisse@cuckoo.hack.org>

	* src/testsuite/run-tests (test_program): Added missing single
	quote.

2002-03-20  Niels Mller  <nisse@lysator.liu.se>

	* src/testsuite/functions.sh (at_connect): Put -- between the
	options and the arguments, as that is the correct place according
	to POSIX. 

	* src/testsuite/lsh-7-test: Rewrote !command-expressions as an if
	expression, to work with /bin/sh.

2002-03-20  Niels Mller  <nisse@cuckoo.hack.org>

	* src/io.c (address_info2sockaddr): Zero-terminate the
	default_preferences list.

	testing run-tests.

	argument list to mini-inetd, appearantly Solaris' getopt
	doesn't handle that. 

2002-03-19  Niels Mller  <nisse@lysator.liu.se>

	* src/io.c (address_info2sockaddr): Prefer AF_INET addresses over
	AF_INET6 (as it seems common that localhost has an ipv6 address
	that doesn't work). Even better would be to try all addresses, but
	that has to wait for later.

2002-03-19  Pontus Skld  <pont@docs.uu.se>

	* src/sftp/testsuite/*-test: grep -q is XPG4, which not all
	greps (notably Solaris /bin/grep) are.
