I've attached three screenshots of the complete measure.  The measure is in 12/8 time, key of E Maj.  The 
first attached screenshot, "desired.png", is what I'd like to achieve.  I created this image by 
"photoshopping" the second attached screenshot, "without_gliss.png".

The "without_gliss.png" screenshot was obtained from the following code.  I've 
highlighted the line corresponding to the part that I'd like help with.  Basically, in 
the second line of the code, I want a glissando from the F# to the G#, and one from the D 
to the E:

< e'\4-3 gs'\3-2 b'\2-1 e''\1-1 >4
fs'16\3-2 d''16\1-1 < gs'\3-2 e''\1-1 >8 % <=== Need help with this line
< fs'\3-2 d''\1-1 >8 < e'\3-2 cs''\1-3 >8
< d'\3-2 b'\1-3 >8 < cs'\3-2 a'\1-1 >8 < b\3-2 gs'\1-3 >8
< a\3-2 fs'\1-3 >8 < gs\3-1 e'\1 >8 < fs\4-3 d'\2-2 >8

The closest I've been able to come is shown in screenshot 
"best_I_have_found.png", corresponding to the following code:

< e'\4-3 gs'\3-2 b'\2-1 e''\1-1 >4
<< { \stemUp fs'8\3-2 \glissando \override Fingering.staff-padding = #2.9 
\single \hide Flag gs'8\3-2 \stemNeutral } \\
{ \stemUp s16 \override Fingering.staff-padding = #2.5 d''16\1^1 \glissando \override 
Fingering.staff-padding = #4.5 e''8\1^1 \stemNeutral } >>
< fs'\3-2 d''\1-1 >8 < e'\3-2 cs''\1-3 >8
< d'\3-2 b'\1-3 >8 < cs'\3-2 a'\1-1 >8 < b\3-2 gs'\1-3 >8
< a\3-2 fs'\1-3 >8 < gs\3-1 e'\1 >8 < fs\4-3 d'\2-2 >8

Basically, I used two voices so I could attach the glissandi properly.  But 
that lead to all sorts of other complexities involving forced stem directions, 
suppressing extra flags, fingering notation positioning, etc.

Also, I haven't found a way to get the F# in the first voice to be of the 
correct duration.  If I try to make it a sixteenth note, then I get a bar check 
error, and if I try to put a hidden rest after it to fix the bar check, then 
that breaks its glissando.
