<pre>PR21482 (fix in r221841) addressed long path name support in the Path corner
of libSupport. However there are also some path-name related Windows API calls
in Support/Windows/Program.inc that could benefit from the same treatment.
RedirectIO() should be updated for long path names. The widenPath() function
in Path.inc could be promoted to the path:: namespace for this purpose.
Execute() does various things; the place that handles the actual program name
should be updated for long path names, unless we decide that it would be
stupid to put an executable program in a directory where CMD.EXE couldn't
find it, and therefore in practice is not a problem. The other places that
use UTF8ToUTF16 in that function look like they're not path-related.
I looked at all other calls to UTF8ToUTF16 and they all looked like they
did not need the long-path-name treatment (uses were e.g. file encoding,
or passing environment variable names to Unicode APIs).</pre>
