Subject: getrichacl(1) man page review comments

Hello Andreas,

Here, some comments on the getrichacl(1) page.

In man-pages, at least, the convention is to use lower case for these
pieces (and thus through the remainder of the page), so:

> .RI [ option "]... [" file ]...

> .SH DESCRIPTION
> For each file, getrichacl displays the file name and Rich Access Control List

For man-pages, at least, the convention is that the references to the
function/command name explained in the page are bold, do:

.BR getrichacl

> (richacl).

For what it's worth, I think it would be worthwhile to start with
a consistent abbreviation comment here (and use it throughout all of the
man pages): "RichACL" (or "richACL"), rather than "richacl"; that seems
more consistent with the traditional abbreviation "ACL".

Use

.BR getrichacl

And then:

.BR acl (7)), it prints [...]
