Re: can a and d be the same for asort?

[Peng Yu]

Since the manual does not say a and d can be the same or not, to be
complete, it should be clearly documented that they should not be the
same.

For example, man strcpy made it clear when such ambiguity occurs.

https://man7.org/linux/man-pages/man3/strcpy.3.html

"The strings may not overlap, and the destination string dest must be
large enough to receive the copy."

I don't know if there is any benefit. That is why I think this should
be documented.
