fixps: a fatal bug, with a fix

[Arnold Boothroyd]

The  fixps 1.6 (GNU a2ps 4.13)  shell script (with Linux Fedora Core 5) 
can fail with an error message such as

mkdir: cannot create directory `/tmp/fixps.WP4474': File exists

This appears to be due to the fact that the command (near the beginning of 
fixps) creating the temporary directory with mktemp, namely:

  tmpdir=$(mktemp -d /tmp/$program.XXXXXX)

is followed (near the middle of fixps) by another command to created this 
temporary directory with mkdir, namely:

  mkdir $tmpdir

This bug appears to be fixed by adding a test for the existence of the 
temporary directory around this latter statement, converting it to:

  if ! ( test -d $tmpdir ) ; then
    mkdir $tmpdir
  fi

Best wishes,
