So I fixed an entirely different problem! How about that?

Aha! So that's what's doing it. They don't on mine.

I'm not an awk programmer either, but I think this is a bit tidier:

user=`echo "$a      
$b                  
" | awk 'BEGIN { OFS=""} { if ($5 ~ /^[0-9]+$/) { print $3; exit; } }'`


group=`echo "$a
$b                     
" | awk 'BEGIN { OFS=""} { if ($5 ~ /^[0-9]+$/) { print $4; exit; } }'`


[Note: I have left the real newlines in for those who *do* want to have
bash as their /bin/sh.]

1 problem. 2 bugs fixed. I reckon that makes my Efficiency 200% :-)
