Hum, this is no easy question. The core problem is, pdftex and repstopdf are
different processes, and there is currently no way for repstopdf to know which
options were passed to pdftex.

A possible way to solve this problem would be :
- make --shell-escape imply openout_any=a and openin_any=a;
- change the \write18 code so that a few critical values (such as shell_escape
and open{in,out}_any) are copied in the environement of the child process.

It looks like the long-term correct fix to me, but of course, such changes are
not going to happen before TL2010 is released.

PS : in the meanwhile, \esptopdfsetup{program at epstopdf=epstopdf} should to the
trick.
