[tap] More uncertainty about junk lines

[Andrew Rodland <[e-mail]>]

Once again I'm working on my parser and trying to deal with some
ambiguities, and I'm realizing that I may be mistaken about the handling of
junk lines. What does "any line that does not parse must be ignored" in the
draft spec really mean? Does it mean lines that couldn't possibly be TAP in
any position (in which case we can still throw an error on out-of-sequence
TAP) or does it mean any line that can't parse in *this* position, in which
case there are no true parse errors at all? In other words, is this TAP:

1..3
ok 1
ok 2
1..1
ok 3

valid with an ignored fourth line, or does it have an error on the fourth
line?
