Log Message:
-----------
Within plGetFam restore initial page status (which is necessarily AT_BOP for
current plGetFam usage) after the plP_init call. This solves a bug where
pages without a change to pls->page_status (e.g., empty pages and pages
which consisted just of text such as the last few pages in example 23) were
indirectly turning plP_eop into a no-op for familying because plP_init sets
the page_status to AT_EOP.
