a2ps psset postscript corruption (^Ountdictstack)

Problem with solution:
 http://bugs.gentoo.org/show_bug.cgi?id=126403

Earlier posting of problem:

Problem: psset -d creates corrupt postscript.  The shell script has a
missing space in a sed s/// invocation.

It's caused by an attempt (using sed) to escape leading whitespace in a
postscript fragment for insertion by a sed filter; it actually inserts a
backslash at the start of every line.  It's this which causes the final
sed filter invocation to see \countdictstack, \c for control, control-O,
resulting in ^Ountdictstack.

Fix is to only escape a leading space with a backslash, instead of
inserting a backslash at the start of every line.
