Changelog
Daniel S (20 Nov 2007)
- Fixed a very long-lasting mprintf() bug that occured when we did "%.*s%s",
since the second %s would then wrongly used the numerical precision argument
instead and crash.
- Introuced --data-urlencode to the curl tool for easier url encoding of the
data sent in a post.
Daniel S (18 Nov 2007)
- Rob Crittenden fixed SSL connections with NSS done with the multi-interface

If this option is used several times, the ones following the first will
append data.
.IP "--data-urlencode <data>"
(HTTP) This posts data, similar to the other --data options with the exception
that this will do partial URL encoding. (Added in 7.17.2)
The <data> part should be using one of the two following syntaxes:
.RS
.IP "name=content"
This will make curl URL encode the content part and pass that on. Note that
the name part is not encoded.
.IP "name@filename"
This will make curl load data from the given file, URL encode that data and
pass it on in the POST like \fIname=urlencoded-data\fP. Note that the name
part is not encoded.
.RE
.IP "--digest"
(HTTP) Enables HTTP Digest authentication. This is a authentication that
prevents the password from being sent over the wire in clear text. Use this in
