Well, I think I got it:

poster skips all lines beginning with a percent sign (treating them as 
comments), but it is legal for ascii85 strings to be split into several 
lines, and these lines legally may start with a percent sign.

To settle this issue, poster would have to syntactically parse the 
PostScript input in order to identify those ascii85 strings which, I think, 
is a major task. Probably it is more convenient to re-implement poster (at 
least to a certain extent) in PostScript itself. I'll think about it.
