DISTFILES+=     oink-${FOO}
SITES.${FOO}=   ${MASTER_SITE_GITHUB:@url@ \
                    -${url}piggy/wiggly/blob/oink/${FOO} @}

DISTFILES contains the filenames as they appear in DISTDIR. Therefore
the oink needs to go in there.

The URL from which to download the file doesn't need the oink prefix. It
deviates though from the usual convention that the URL ends with the
DISTFILE. When prefixed with "-", a fetch URL does not have the DISTFILE
appended to it.

If you don't like the :@ modifier, you can also do the URL
transformation in two separate steps:

SITES.${FOO}= \
    ${MASTER_SITE_GITHUB:S,^,-,:=piggy/wiggly/blob/oink/${FOO}}
