bad link to curl-config

[jay]

In the LINKING section of libcurl doc there is a bad link to curl-config:

https://curl.haxx.se/libcurl/c/curl-config.html

The correct URL is:

https://curl.haxx.se/libcurl/using/curl-config.html

libcurl/c/Makefile has DOCROOT=$(SRCROOT)/docs passed to roffit to generate the links, and curl-config doc is in the libcurl repo at docs/curl-config.1 so I don't know why it isn't finding the file. It may be a bug in roffit? What is cvssource? I assume an old name that now is the expected location for the git repo?

curl-www/libcurl/c/Makefile

Yes, cvssource is a link from the web repo to the soure repo (see https://github.com/curl/curl-www/blob/master/bootstrap.sh) and the name was picked back in the old days as you might've guessed.

This bug is indeed roffit related or perhaps because of the way we use roffit on the site. I'll fix it now with a redirect in the apache config.
