Fix vuprintf fix possible %s buffer over-read
when precision is not specified memchr recieved -1 for count
count is unsigned so it looks in a potentially very large area
for a terminator and returns this whole area if \0 is not found
Instead we should use memchr when precision is specified
and if precision is not specified use strlen
Fixes 60+Mb Config.cfg files
