 My pickup has a hydraulic clutch that I had to "re-engineer". Just about
 every thing on it is plastic. master cylinder, slave cylinder, and the
 lines. And the line is NOT reinforced plastic. It is just a poly type
 plastic hose. I have it spliced with just a standard plastic airline
 fitting.
 There is not that much pressure in the hydraulic clutch system to worry
 about line expansion.
 I would suspect that you have a high spot in the system that is trapping
 the air. the bleeder valve should be the highest point. >>

Yeah, my 93 chevy truck is like that (plastic tubing for the line), and they 
put the bleeder right on the end of the slave too, right at the lowest point 
of the vehicle. I've found that I have to jack that side up as high as I can 
get it, so it will bleed.  I do agree, that it sounds like you've got an air 
pocket in there, but pumping it up shouldn't really add length, only firm up the 
pedal. If it's adding length, then you still have some more adjusting of the 
rod to do. I hope this helps.
