Fix some problems with REFETCH mods:

1. don't hardcode true, echo and [
2. Cope with distfiles which are located in a DIST_SUBDIR
3. Don't always assume there will be a size field in the ${DISTINFO_FILE}

XXX The refetch mods make an assumption that an exit code of 0 from a
${FETCH_CMD} means that the transfer has been completed successfully,
and this used not to be the case.  I haven't tested this assumption
recently.
