And gs is correct doing so, since
Encapsulated PostScript 
File Format Specification 
Version 3.0
says, in the section "Guidelines for Creating EPS Files":

 The two required DSC Header comments are

%!PS-Adobe-3.0 EPSF-3.0 
%%BoundingBox: llx lly urx ury

Thus, we have to add the following to the sed command line
 -e '/^%!PS-Adobe-3.0/s/$/ EPSF-3.0/'

You may check the results in attached file epstest2.tgz
Of the result files in that archive 
foo.png looks OK (no parts cut off from the letters).
(foo.eps shows OK too in Mac OS X Preview, but I am not
sure how that application works).

Please, compare the results with what is generated/shown in your environment.

Let us first see whet happens to an extremely simple ps file
in different environments (see attached file croptest.tgz).
