pline bits

a few plines that were without punctuation.  There may be more non-DEBUG
pline or pline-like things that are still missing punctuation.  They are
almost impossible to find after the fact, since they could be anywhere,
including in various dat files and functions that pass strings and formats
into other functions that call pline.
