72089cf6b4 config: deindent all help texts
Those two spaces after tab have no effect, and always a nuisance when editing.

9a647c326a separate TLS code into a library, use in in wget
A new applet, ssl_client, is the TLS debug thing now.
It doubles as wget's NOMMU helper.
In MMU mode, wget still forks, but then directly calls TLS code,
without execing.

This can also be applied to sendmail/popmail (SMTPS / SMTP+starttls support)
and nc --ssl (ncat, nmap's nc clone, has such option).

a6f8651911 wget: fix for brain-damaged HTTP servers. Closes 9471
write(3, "GET / HTTP/1.1\r\nUser-Agent: Wget\r\nConnection: close\r\n\r\n", 74) = 74
shutdown(3, SHUT_WR)    = 0
alarm(900)              = 900
read(3, "", 1024)       = 0
write(2, "wget: error getting response\n", 29) = 29
exit(1)

The peer simply does not return anything. It closes its connection.

Probably it detects wget closing its writing end: shutdown(3, SHUT_WR).

The point it, closing write side of the socket is _valid_ for HTTP.
wget sent the full request, it won't be sending anything more:
it will only receive the response, and that's it.
