It is in fact better not to think about fixing the eps but about
building a PostScript page around it.

The code below is a PostScript file with an eps included according
Adobe recommendations:

%!PS-Adobe-3.0
%%BoundingBox: 0 0 72 72
<< /PageSize [72 72] >> setpagedevice
gsave
72 10 translate
save
/showpage {} def
%%BeginDocument

%% 8< snip

%!PS-Adobe-3.0 EPSF-3.0
%%Title: square.eps
%%BoundingBox: -72 -10 0 62
newpath
 -72 -10 moveto
 0 -10 lineto
 0 62 lineto
 -72 62 lineto
 closepath
.5 setgray fill

%% 8< snip

%%EndDocument
restore
grestore
showpage

The middle part is the unmodified original eps, except for stripping
a preview header if necessary.

It should be safe to assume that if a boundingbox comment
doesn't occur in the first 1000000 bytes, and a deferred boundingbox
comment not in the last 1000000, then it won't be there. So you
don't have to slurp the entire eps in the search for boundingbox
comments.
