data file names with a '.' as the first character. I've taught
opkg how to cope with the presence or absence of the '.', but
this may trip up dpkg.
For all I know, this could actually be a bug in opkg-build. So,
I'll have to try installing some .debs and comparing the *.list
files.
If we wanted to, we could workaround the deb_extract behavior
right here, by writing to a tmpfile, then munging things as we
wrote to the actual stream. */
