[pca] Latest pca no longer downloading patches from sunsolve

[Martin Paul]

Greg,

Not sure whether I'm on the right track, but ..

I notice that your examples with "http" URLs go through a local proxy 
(humr.rl.gov), while those with "https" connect to sunsolve directly. 
Maybe you must use the proxy for HTTPS connections, too?

As I don't see pca's "--wgetproxy" option being used, you maybe set 
"http_proxy" in some wget configuration file (/etc/wgetrc, ~/.wgetrc). 
For HTTPS connections, you will need to set "https_proxy" as well.

In the current release of pca, it always uses HTTPS for xref/patch 
downloads when it finds a wget binary with HTTPS support; that's why 
this might appear like a new issue for you.

Martin.
