My bulk indentation check also turned up a lot of cases where a run-on
function call or if statement didn't have its later lines aligned
correctly relative to the open paren.
I think this is quite easy to do by getting things out of
sync (editing the first line of the function call and forgetting to
update the rest, perhaps even because you never _saw_ the rest during
a search-replace). But a few didn't quite fit into that pattern, in
particular an outright misleading case in unix/askpass.c where the
second line of a call was aligned neatly below the _wrong_ one of the
open parens on the opening line.
Restored as many alignments as I could easily find.
It's a thoroughly pedantic point, but I just spotted that the
comparison of wire data against theoretically platform-dependent char
escapes is a violation of \k{udp-portability}.
Ian Jackson recently tried to use the recipe in the psusan manpage for
talking to UML, and found that the connection was not successfully set
up, because at some point during startup, UML read the SSH greeting
(ok, the bare-ssh-connection greeting) from its input fd and threw it
away. So by the time psusan was run by the guest init process, the
greeting wasn't there to be read.
Ian's report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=991958
I was also able to reproduce this locally, which makes me wonder why I
_didn't_ notice it when I originally wrote that part of the psusan man
page. It worked for me before, honest! But now it doesn't.
Anyway. The ssh verstring module already has a mode switch to decide
whether we ought to send our greeting before or after waiting for the
other side's greeting (because that decision varies between client and
server, and between SSH-1 and SSH-2). So it's easy to implement an
override that forces it to 'wait for the server greeting first'.
I've added this as yet another bug workaround flag. But unlike all the
others, it can't be autodetected from the server's version string,
because, of course, we have to act on it _before_ seeing the server's
greeting and version string! So it's a manual-only flag.
However, I've mentioned it in the UML section of the psusan man page,
since that's the place where I _know_ people are likely to need to use
this flag.
This clears up another large pile of clutter at the top level, and in
the process, allows me to rename source files to things that don't all
have that annoying 'ssh' prefix at the top.
