This is a problem that can only get worse, because binary passages
in PS files are bound to become ever more bloated.
The Macintosh -> UNIX/Windows problem can be solved in all sorts
of messy but simple ways, (I use tr) but the long binary
problem is going to be a lot worse. No matter how large the TeX
input line buffer is made, some application is going to produce
a binary even longer. Moreover, any binary is likely to include
an \012 or \015 character somewhere in it, and TeX is, not surprisingly,
going to breathe a sigh of relief and regard that buffer as
terminated. I suspect that TR is looking at the only
workable solution, which is to recode the Binary passage into
Hex, or something similar which permits lines of a reasonable
length. I presume---I certainly hope---that a passage translated
from binary to ASCIIHex or ASCII85 will be successfully be
retranslated by any competent PostScript interpreter.
Since %%BeginBinary and %%EndBinary are not likely to
have anything else nested between them, a Perl translation ought
to be not too complicated. (No, I am afraid I am not volunteering.
I do Perl, but not nearly well enough to expose my programming
style to public scrutiny.)
