Technically, in Unix world any file is a hard link. It is impossible to
distinguish a hard link from the "original", they are completely equal.
So I don't think that there will be a ambiguity, what links are implied,
especially, if the documentation is clearly says "symbolic links".

Technically, they are local variables.

As "getgrouplist" or "sendfile". What about such argument names as
"filename" and "newline"? If being a consistent in that, then it must be
"follow_symbolic_links". And "source_directory_file_descriptor" instead
"src_dir_fd".

I agree.

Of course. This is the issue, for the solution of which I registered
here. All other issues and patches were just distractions and
practice. ;-)  I am grateful to you.
