Bugfix for the pdiff program

The postscipt files generated by pdiff display the old-part of the changed text as solid black rectangles.

The apparent culprit is the file diff.pro (the PostScript Prologue file for a2ps), which is usually located at /usr/share/a2ps/ps/diff.pro. You can replace your diff.pro file with my modified diff.pro.

The modificarions made are (unified diff):
