Latest xemacs build gave:-
  Finding  Requires: (using /usr/lib/rpm/find-requires)...
  objdump:
/var/tmp/xemacs-root/usr/lib/xemacs/xemacs-packages/lisp/sh-script/executable.el:
File format not recognized

This is due to in find_requires:-
  exelist=`echo $filelist | xargs -r file | fgrep executable | cut -d: -f1
`

which misidentifies the .el file as executable because its name contains
"executable".

if the grep is changed as per the script list one, so its:-
  exelist=`echo $filelist | xargs -r file | egrep ":.* executable" | cut
-d: -f1 `

then that cuts out all the false positives - I can see no false negatives
that this will add.
