Correct some style nits that I have mistakenly submitted as

suggestions which result in the last revision[*]: - style(9) and sysexits(3) suggests that we use EX_* as exit values, instead of some other values like those returned from a system call as errno. Additionally, follow Ruslan's suggestion about style(9) and other style improvements: - Since open(2) says that it returns -1 on errors, explicitly determine whether it is returning -1 rather than whether the return value is less than zero. - Only set rval when there is no previous error. This distinguishes the first error that occours. - Use exit() in favor of return in main(), this is suggested in old style(9), while the evolve has fade the suggestion. - Add some NOTREACHED comments. - Add blank line after first { because no local variables in usage() Thanks to Ruslan for his tireless explaining of the code standards and knowledge of the history of style(9).
