Sorry, but then I must be the one that is blind.

I cannot see that the manual entry documents any result of calling sbrk
with an argument different from 0. If this is the intention (in order to
deprecate use of sbrk with other arguments), IMHO this should be more clearly

BTW, I don't understand the wording in "Data addressing is restricted between
addr and the lowest stack pointer to the stack segment." What does lowest
refer to? And what is the stack segment? Note that even if I interpret it
according to my a posteriori knowledge of the semantics of U*X systems, it
is wrong anyway, since there might be mmap'ed data in this area.
