Summary
  • Use -r for "reverse" mode and to match DragonFlyBSD.
  • Move defines around to clear up logic
  • use errx instead of fprintf and exit

A and B and C reads badly

try: "only one of -l, -s, and -D may be used"

I like this re-organization to avoid #undef ugliness... Please do mention it in the commit message

Can you rename this to Dflag to match the case of the flag, given that there's also a -d?

Can you throw these tokens in a separate #define up above as well? DELIMITERS or something to that effect.

Also, style(9) spaces around =

This doesn't seem to match the given commit message, which indicates that the flag was called -r

440

This one seems to have actually been missed; the braces should be omitted here like on the other one-line blocks.

I reckon this will be the last round. =)

These left more inconsistent omission of braces for single line blocks, but otherwise also a good change that should be noted in the commit message. =)

renamed to rflag to match dragongflybsd.

440

I went the reverse: adding braces to all single line blocks. style(9) makes it optional, I prefer it.
