like this is needed please resubmit for Intel's approval.
Update to mandoc cvs version as of 20141201
- Compatiblity with existing manpages has been improved
- Now support ".so" directive with compressed manpages (which fixes a regression
we have since we have new man(1))
Revert r274953, r274934

mandoc(1) is now able to display correctly the vanilla version
Remove unused PCMCIA_CARD* macros.

Always include the card human readable name. We support ~270 cards and
at ~20 bytes each, this bloats things by only ~5k. Retain the
PCMCIA_CARD vs PCMCIA_CARD_D distinction, though, in case this is
intolerable.
Add sleep(1) to /rescue.  This adds 664 bytes to the binary on amd64 but
it's pretty useful for shell scripts.
