[l2h] pstoimg: using -multipage options should use zeropadding

[Roland Stigge]

Hi,

a Debian user reported the following wishlist "bug":

=======================================================================
The option -multipage results in files ending with numbers. When
converting a document with more than 9 pages it results in:

  doc1.png
  doc2.png
  ...
  doc10.png

A filename listing therefore would result in:

  doc1.png
  doc10.png
  doc2.png
  ...

It would be nice if pstoimg would zeropad the numbers appropriate,
when the document has more than 9 pages (and maybe when it has more
than 99 pages again), resulting in:

  doc01.png
  doc01.png
  ...
  doc10.png
=======================================================================

Thanks for considering.

bye,
  Roland
