l10n problem in a2ps

I noticed a problem in a2ps linked to localization. In the PostScript output a2ps generates, several real numbers are present. These numbers are I suppose (I did not look in the source) using the libc printf function calls. Those functions change their output depending on the value of the LANG environment variable.

If LANG is set to fr_FR.ISO8859-1 (other values might cause the problem also), then floating point numbers are displayed using ',' as the decimal separator. The resulting PostScript file is therefore corrupted since PostScript only allows the dot as a decimal separator.

Generating the same file with no LANG variable set solves the problem, although the date format and possibly other output are not conformant to the user's initial choice.

I think a2ps should produce correct PostScript output no matter the value of the LANG variable.

Best regards and thanks for a2ps,

Mathias Herberts.
