There've been a few threads on this in the various BSD camps (and among 
a group dealing with OSes where I work) ... Suggestions have ranged from 
ripping out stdio in these programs (using write(STDOUT_FILENO, ...) 
instead) to suggestions such as yours...

I guess it boils down to "where do you draw the line?"  Are you willing 
to give up potentially useful functionality (in this case, looking up 
error messages in the message catalogue) or ease of implementation (not 
using stdio :-) ... in many cases, the end (a marginal gain in disk 
space) doesn't really justify the means...

On that note, I'd like to solicit other opinions on this subject...
