[pca] some readmes are sometimes not fetched correctly

It would be interesting to know why the downloads fail for you. You can 
check that with pca's "--debug" option.

Actually, pca already does a lot to ensure that downloads are 
successful: It uses wget, which does a very good job at dealing with 
slow or hanging connections. Plus, it has a "--dltries=NUM" option which 
will retry failed downloads with rising intervals.

The most frequent issues with downloading files from SunSolve are not 
because of slow connections which time out, though, but with the Sun 
webserver turning down a dowloading request with an "internal server 
error" immediately. There's not much pca could do to workaround those.
