Clarify in unlink(1) that like rm, unlink too requires "--"

[dteske]

Summary

While it is explicitly stated with rm that "--" and "./" are methods
for removing a file with rm, the paragraph on unlink is misleading.
Add that unlink too supports "--" and change the wording so that it
is clear that unlink does process arguments, just that none are supported.

I agree that the man page should be changed, but I think it can be done better.

bin/rm/rm.1

"argument" should be changed to "operand", per POSIX's definitions.

I would like to see this addition with the corresponding note about rm in NOTES instead of separately here.

This is a common enough FAQ. Do we need it in the manual? Also, some circles recommend ./-f instead of -- -f.

I'll leave that for someone else to battle ...

There is already a note about this and "rm", just scroll down.

The note about ./-f is already in the manual, just scroll down.
