In getfacl(1) manual page, mention where to read about the ACL syntax.
PR submitter suggested adding it to acl(3) instead, but I don't think
pointing ordinary users at section 3 is a good idea.

More mdoc nitpicking to improve compatibility to mdocml

- .Nd in section NAME is not optional
- .Ed was missing
- "indent" is not a flag, but a literal argument for -offset
- stop switching font sizes for acronyms
- use .Brq instead of rolling our own

Use our canonical .Dd format.

Add the new standard EXIT STATUS section where appropriate.
Sort standard sections in the (documented) preferred order.

Fixed spelling of the document date.

Grammar.

Add "-h" arguments to getfacl and setfacl, which behave in a manner
similar to "-h" on chown, chmod, etc, causing the operation to occur
on a final symlink in the provided path, rather than its target.

- Consistent use of warn() vs. perror().
- Gracefully handle the case where standard input is missing
a newline at EOF.
- Exit with status 1 instead of -1 (really 255) on error.
- Add a Diagnostics section to the manual page documenting
exit status.

mdoc(7) police: normalize .Nd.

mdoc(7) police: fix markup and some spelling.

o POSIX.2c Userland tool support for POSIX.1e ACLs -- getfacl retrieves ACLs
