fix(docs): missing "(" in :help HTML

Browse Source 
Problem:
Since eba7b5b646
any opening paren and its leading whitespace " (" are missing in the
generated HTML. Example:

    Use ":qa!<Enter>" (careful, all changes are lost!).
                     ^^missing
    Position the cursor on a tag (e.g. bars) and hit CTRL-].
                                ^^missing

Solution:
The main recursive loop only processes named children, so check
named_child_count() instead of child_count().  Then anonymous nodes
won't get lost.
