David,
DIRECTORIES:
The situation for directories seems pretty clear to me, and much the same as how
Philip saw it (I think). From 6.2.4, item 16 (page 157, lines 4-11):
The line number program assigns a number (index) to each of the directory
entries in order, beginning with 0.

Lets see if we can get a complete picture of the
indexing into the line table header directory/file
names tables.
The conjecture at the end of this suggests that
all places with an actual file/directory number
or index should be 1-origin, reserving 0 to
mean no file named.
