I didn't get a chance to see if wget was installed on previous versions of  
OS X before leaving work today, but I don't recall ever having installed  
it on 10.6 or 10.10.  So maybe that's something new with 10.12?

The reason I switched was because wget is available with msys, but curl  
isn't.  I dug up some Windows build of curl a few months ago, but don't  
recall where.  Maybe it's still in my browser history at work.  I seem to  
have a /mingw/bin/curl on my home system, and vaguely remember building  
that from source a long time ago.

Since I doubt many (any?) people run the tests on Windows, I don't have a  
problem with switching back, if how to install curl is documented on the  
page describing how to run tests on Windows.  I forget if I made similar  
changes in core Mercurial.
