>Description:
The expression ${line%%/\**} should return the leading part of $line, cutting off the first occurrence of /* and everything that follows it.
Currently, the \* is not handled as specifying a * character, but is essentially equal to giving a plain * character.

This change seems to break many /etc/rc* (and indirectly) *.mk stuff
of a regular NetBSD system. I noticed that first during
/etc/rc.d/network start, when some ifconfig.XXX were no longer set up.
Also /usr/sbin/postinstall check now produces some 'additional'
output.
Just reverting this change seems to fix it.
Markus.
