Correctly localized strings

This first part of your patch seems fine.

This second part has a problem though.  On some, older, systems,
isprint() is only defiend to work on values that are accepted by
isascii() and using values outside of that range will produce
segmentation faults. 

I think that perhaps this part of your patch:

> -#ifdef isascii
> -#define isgraphic(c) (isascii (c) && (isprint (c) || (c) == '\t'))
> -#else
>  #define isgraphic(c) (isprint (c) || (c) == '\t')
> -#endif

ought to be changed to:

> +#if defined isascii && ! defined HAVE_LOCALE_H
>  #define isgraphic(c) (isascii (c) && (isprint (c) || (c) == '\t'))
>  #else
>  #define isgraphic(c) (isprint (c) || (c) == '\t')
>  #endif

Does this work on your system ?
