Subject: in backtraces, print as many arguments as the function actually has
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=4ac5ce523aab3cd6f464ae56149e56b2d7ac803c;p=openbsd

in backtraces, print as many arguments as the function actually has

since amd64 is compiled with -msave-args we have all arguments available to print and
there's no reason to limit this to six.
