Maybe grep's concept is simple, but the program itself is not that 
simple. For example, the grep man page doesn't document all the ins and 
outs of PCREs. (Not even the manual does that!)

The GNU Coding Standards are pretty clear that man pages are 
secondary.[1] To some extent the GNU grep man page is already too long 
and detailed. FreeBSD's grep man page[2] is a better length (and 
amusingly, it also doesn't mention the minor detail of files ending in 
non-newline).
