cleanups of this man page. The lengthy description has now also been removed
from curl/multi.h since it immediately got tedious to maintain the info on
two places when I did major updates...

curl_easy_init() if you don't call curl_global_init() explicitly in your app

now to enable them to get added as web pages easier, they are not ready
for anything "real" just yet.

run that might be needed only for building libcurl.

fix CONNECT to a proxy that disconnects during the auth phase

issues in the code.

string in the given error buffer to address the flaw mention on 21 sep 2005.

step counter by adding :[num] within the brackets when specifying a range.

  range increasing the number with 10 for every step. Requested by Jose:

  Curl_ossl_connect(), the Curl_gtls_connect() function does not send the user
  certificate to the peer. In fact, it ignores the conn->data->set.cert field
  completely, it always uses the anonymous credentials. See
  http://curl.haxx.se/bug/view.cgi?id=1348930

 1.9 Where do I buy commercial support for curl?
 1.10 How many are using curl?
 6.7 What are my obligations when using libcurl in my commerical apps?

Edited a few other paragraphs slightly.

(http://curl.haxx.se/bug/view.cgi?id=1338648) which really is more of a
feature request, but anyway. It pointed out that --max-redirs did not allow
it to be set to 0, which then would return an error code on the first
Location: found. Based on Nis' patch, now libcurl supports CURLOPT_MAXREDIRS
set to 0, or -1 for infinity. Added test case 274 to verify.

differences between OpenSSL and GnuTLS (that is probably a suitable subject
for a separate document...)

in the man page, curl would send an invalid HTTP Range: header. The correct
way would be to use "-r [number]-" or even "-r -[number]". Starting now,
curl will warn if this is discovered, and automatically append a dash to the
range before passing it to libcurl.

do not get NTLM support enabled.
