utf-8, printf and .prec

[M G Berberich]

Hello,

GNU Awk 3.1.7, Debian squeeze, amd64

Problem:
The .prec modifier in printf to %s should limit the number of
characters that are printed. This does not work if locale is set to a
utf-8 (multibyte) locale.
As gawk claims to be multibyte-aware since 3.1.5 I consider this a bug.

Reproduce:

# works for non-multibyte-locale
$ echo Halloniergendwo  | LANG=C gawk '{printf("%-10.10s\n", $1)}'
Hallonierg

# does not work for multibyte-locale
$ echo Halloniergendwo  | LANG=de_DE.utf-8 gawk '{printf("%-10.10s\n",$1)}'
Halloniergendwo

        MfG
        bmg
