On a recent build from Github-master, I noticed a lot of slow scans which were waiting for various default SSL scripts such as ssl-cert etc. to timeout.

After some debugging, I think the root cause is the https-redirect script misidentifying plain HTTP services as ssl/http which then causes a load of extra scripts to be run.

More details here: https://github.com/nmap/nmap/issues/1400

I'm not sure if the error is in the script or in comm.tryssl function.

Hopefully the information I put there can help with the fix.

Hopefully fixed in r37530
