Bug#568167: epstopdf: the --nogs option does not work as a filter

[Vincent Fourmond <fourmond@debian.org>]

Package: texlive-font-utils
Version: 2009-7
Severity: normal

  Hello,

  The --nogs option of epstopdf does not work as advertized; according
to the manual page, it should behave essentially as the --filter
option, but only producing the intermediate PS file and not feeding it
to ghostscript. But see:

~ epstopdf --nogs < bidule.ps > /dev/null
[...]
!!! Error: Input filename missing

Whereas:

~ epstopdf --filter < bidule.ps > /dev/null

does not complain.

  If I run it like

~ epstopdf --nogs bidule.ps

then the output file is '-' -- but not standard output. The problem is
that the opening for output file is:

  open($OUT, '>', $OutputFilename) or error "Cannot write \"$OutputFilename\"";

(with $OutputFilename = "-" for --nogs), but perldoc -f open says:

  In the 2-arguments (and 1-argument) form opening '-' opens STDIN and
  opening '>-' opens STDOUT.
  
  In short, opening '-' to get stdout does work as 

open HANDLE, "> -";

  but not as

open HANDLE, ">", "-";

  Cheers,

	Vincent
