To use an up to date download link as well as remove duplicate
information.

It counts "body" data only, no meta data, no headers.

While "just" an example it still isn't nice to leak memory.

-p takes a list of Mozilla trust purposes and levels for certificates to
include in output.  Takes the form of a comma separated list of
purposes, a colon, and a comma separated list of levels.

...and removed ;OPTIONS from --user as that functionality was removed
in 7.34.0.

Mentioned in bug #1342

And clarify for curl that --proxy-header now must be used for headers
that are meant for a proxy, and they will not be included if the request
is not for a proxy.

Updated the docs to clarify and the code accordingly, with test 1528 to
verify:

When CURLHEADER_SEPARATE is set and libcurl is asked to send a request
to a proxy but it isn't CONNECT, then _both_ header lists
(CURLOPT_HTTPHEADER and CURLOPT_PROXYHEADER) will be used since the
single request is then made for both the proxy and the server.

... and sorted the list

Modified the logic so that CURLOPT_HEADEROPT now controls if PROXYHEADER
is actually used or not.

Includes docs and new test cases: 1525, 1526 and 1527

This limitation was removed in commit 0bc4938e

In the initializer for len, there is no prototype for "strlen".
In this statement, there is no prototype for "memcpy".

Also fixed a function name change in the version requirement bump

The information about building with Kerberos4 support was half a year out
of date. We dropped support for that.

Added initial support for --next/-: which will be used to replace the
rather confusing : command line operation what was used for the URL
specific options prototype.

... and mention the --tlsv1.[0-2] options in the --tslv1 entry
