Thanks.  I _think_ you ended up not having to use shell function to
avoid code duplication ;-) but I find the script part of the result
much easier to understand.

Two things I noticed:

 - run-windows-build.sh did not use to run with "set -e" but now it
   does because it includes lib-travisci.sh; if (I didn't check with
   fine toothed comb) the original were not "set -e" clean, we may
   see unwanted errors in run-windows-build.sh, but that is
   sometihng we can fix going forward.

 - it seems that the test output section lost ": <- click here...";
   I do not know if there is a negative consequence of this change.

Indentation of some scripts were a bit too deep and I found it hard
to read them, so the following is what I did (but did not commit)
while reading them through.

Thanks.
