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.

A bit of thought, and it becomes clear. Since 0 is a reserved
(and always has been)
value for DW_AT_decl_file the numbers used by the compiler
must start at 1.
So to index into the array of names from the line table header
make sure your value is greater than zero and
subtract 1 from the DW_AT_de
