openssl-env allows the use of the environment variable of the same
name.  This reminds me a bit of the recent interferences with GZIP,
for example.

This patch is missing one addition of set_single_env() in
vcregress.pl, and one update of install-windows.sgml where all the
supported environment variables for commands are listed.
