Subject: After opening all the needed files, tighten the pledge(2)
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=5117cd2872e582a1233cdfaea7760eb050235d5c;p=openbsd

After opening all the needed files, tighten the pledge(2)
from "stdio rpath" to just "stdio", before parsing any user data.
It may not matter that much just yet, but parsing will become
slightly more complicated soon when i shall add UTF-8 handling.
OK millert@
