[tex-k] epstopdf doesn't like --filter and --outfile option together

This is due to the section around line 304 in epstopdf.pl:

if ($::opt_filter) {
  debug "Filtering: will write standard output";
  $OutputFilename = "-";
} else {
  debug "Output filename:", $OutputFilename;
}

which should presumably be replaced by the single line:

debug "Output filename:", $OutputFilename;

There is a slight contradiction in the manpage for epstopdf, where
only the explanation of --outfile suggests that --filter overrides
--outfile; presumably, this should instead say "If --nogs or --filter
is specified, the default is to write to standard output."  Here are
the relevant parts:

  --outfile=file
         write result to file; the default is  to  construct  the output
         file  name  by  replacing  any  extension in the input file with
         .pdf.  If --nogs or --filter is  specified,  write  to standard
         output.
[...]
  --[no]filter
         read standard input (default: off).
[...]

EXAMPLES
  Examples for producing "test.pdf":
  epstopdf test.eps
  produce postscript | epstopdf --filter >test.pdf
  produce postscript | epstopdf -f -d -o=test.pdf
