This is an interesting topic, Eric!

In bar 1, 9 and 17 the grace note gets 50% of the duration from the note it belongs to, because there's not a little line through the grace note. But I hear some of you play the grace note much shorter.
To be honest I didn't notice that the little line was missing, which according to Wikipedia makes it an appoggiatura
instead of an acciaccatura
, and should therefore have more even duration between the two notes. I just followed the way M. Delcamp plays it (or at least how I thought he played it). There's yet again some confusion of terminology, as sometimes people just refer to long and short appoggiaturas, and acciaccatura refers to a non-harmonic note played either at the same time or slightly before a chord (that interpretation is surely more relevant with piano than guitar). I also understood after some research in internet, that modern editors do not use long appoggiaturas anymore, but they are instead written as two notes of equal duration (and same font size) with a slur between them.
I also checked 'The Complete Works of Agustin Barrios Mangore' by Rico Stower, and he uses the little line in those places making it a short appoggiatura or an acciaccatura, whatever you wish to call it. Therefore I tend to think that the 'g' should be played short rather than long. Another significant difference between the short and long versions is that in the long one the grace note is accented (as it occurs on the beat), and the following note is not, which I think would sound strange in the context of this piece (with long appoggiatura the transition from the grace note into the main note usually resolves tension, which I think is not the case here, as the tension is relieved only when returning to 'e'). With short appoggiatura the latter note gets the accent.

Mister Delcamp plays a glissando himself and I like that, but in my modest opinion that's not what the score says. In that case we need to notate also a slur (bowed line) if it concerns two "ordinary" notes. When it concerns a grace note and an "ordinary" note, we don't need the straight line, only the slur. Or am I wrong?
I think you are wrong with your assumption that glissando would require a slur tie. The slur would simply indicate that the latter note isn't played with right hand, or at least played very softly. Grace note without the straight line could imply simply a pull-off or a hammer-on.
Some examples from D05:
- Lagrima, p. 89, bar 9 : Between two notes a grace note connected to the first note with a straight line (no slur tie) indicating : first play the first note, then slide to the pitch of the second note (audibly), then play the second note.
- Romanza bar 5 : Grace note connected to main note with a straight line (no slur tie) indicating : play the pitch of the grace note, then immediately slide into the main note (audibly), but do not play it again. I read somewhere that grace notes are always assumed to be slurred into the main note, so the use of slur tie is not mandatory.
- Ländler p. 76, bar 8: Two notes connected with straight line and a slur tie indicating : play the first note, then slide to second note (audibly) but do not play it.
- Ländler p. 76, bar 12: Between two notes a grace note connected to the second note with a straight line and a slur tie indicating : Play the first note, then play the first note again, and immediately slide (audibly) into the pitch of the second note, but do not play the second note (again).
- El sueno de la Munequita, bars 21 and 23: Could be shorthand for Lagrima case, or could simply indicate a guide finger (non-audible slide), or could indicate "do it however you want to". But I personally think it's the first case, because otherwise the fingering wouldn't make any sense. Why use the same finger for those notes unless the purpose is to produce an audible slide?
Just my 2c and some change...
