- This assumes that "the market" purchases systems based on the
- format of the output of who. This is not the case, but that is not to
- say that purchasers of Unix systems would not like their machines to all

- This will never happen. Vendors have no incentive to standardize
- who (among other things). The only real leverage users can exert to obtain
- properly standardized environments is through the standards process.
- The power of the purse is essentially useless when it comes to little
- things like the output of who and the command line switches of cc since
- no one (to my knowledge) makes purchasing decisions based on these
- criteria. This sort of thing turns into just another annoyance in a
- heterogeneous environment; it is however a pointless annoyance which standards
- can essentially do away with.
