Hi Bart!
You're probably right about the line. If you happen to be able of reading
german literature, there would also be "2000 Jahre Europäische Schriften -
Eine Einführung in die Notationskunde" (roughly translated to "2000 years
of european writing - An introduction to the study of notation") by Karl
Schnürl, published at "Verlag Holzhausen" in 2000. There he describes the
line as "indicating to let the finger on the string." ("[...], die das
Liegenlassen des Greiffingers bezeichnen.") So, while in tablature it's not
always clear how long a note really is (as the only point that's clearly
defined is where the note begins) at least this gives an indication that
those notes should definitely be longer.
(Although before you run and buy the book: to be honest, it's more a
compendium about many things. But it was used by my
study-of-notation-professor at university to make us familiar with
tablature as it covers most things on relatively few pages.)
All the best
Christian
