re: "Would this happen if the clutch disc was stuck to the flywheel?"

I think if it was just the clutch disk stuck to flywheel you'd still get 
at least some movement of the pedal. Early cars used coil springs in the 
cover plate to hold the disk firm to the flywheel, and later cars used 
diaphragm 'springs.' I think with either you'd at least be able to move 
the pedal until the springs reached their limit of travel (or you left 
leg reached its limit of strength).

It's a long shot SWAG, but since the car has sat for a long time it's 
conceivable the fluid in the line has gelled and/or crystallized to the 
point it prevents flow to the slave cylinder (I have had BF gell up). 
I'm not sure you can move the release bearing fork much by hand, though 
I haven't tried; those are some strong springs in the cover plate.
