I made these changes.  I wasn't able to apply the patches
automatically.  In the future, please send patches as text/plain
attachments to avoid line wrapping mailers.

If this is a better way of checking for programs compared to what we
do now, then it would be useful if someone would look at converting
the existing tests to use this style.
