Subject: [PATCH] Paul Moore made curl check for the .curlrc file (_curlrc on
 windows) on two more places. First, CURL_HOME is a new environment variable
 that is used instead of HOME if it is set, to point out where the default
 config file lives. If there's no config file in the dir pointed out by one of
 the environment variables, the Windows version will instead check the same
 directory the executable curl is located in.
