 Priority:  minor           |             Milestone:  someday
Component:  core libraries  |               Version:  5.1.0

 both procedures create a new output file using open, so permissions are
 always (assuming normal umask) 644. this patch sets the permissions to
 those of the input file after writing all bytes and before closing the
 ports. tested on PLATFORM=linux. I do not know the implications of this on
 windows; the fact that C_chmod and C_fchmod have definitions in
 posixwin.scm makes me assume this is safe, but I cannot be sure without a
 machine to test on
