Initially ghostscript_binary is set to "", but a few lines later in the
script
a line similar to this appears (it actually appears in a loop):
ghostscript_binary = file_in_path(EXEC_PATH, ghostscript_binary);
This returns an empty matrix if ghostscript_binary is not in the path.
You could reset ghostscript_binary to "" after the loop if
it is an empty matrix at this point.

I'm in favor of this.
