RFC/PATCH: Fix BSD package completion

[Mikael Magnusson <mikachu@xxxxxxxxx>]

with the last line uncommented (or the unmodified original), completing
/us<tab>
deletes the whole input. Presumably _files doesn't interact well with
adding the same strings in full with a raw compadd. I didn't try adding
something to $PKG_PATH so maybe the middle line breaks too. Fun fact,
that path/paths typo has been there since the initial commit in 2000,
and even so, $paths always contained a single empty element anyway.

To reproduce this on a non-bsd system, just set PACKAGES to some directory
that has All/*.tgz in it.
