Subject: awk-format: Accept null precision.
X-Git-Tag: v0.26~92
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2305b059e2574b51791949062923bbcdc9d2a097;p=thirdparty%2Fgettext.git

awk-format: Accept null precision.

Proof that it's valid:
$ echo 3.1415926 | gawk '{ printf "%.f", $1 }'

* gettext-tools/src/format-awk.c: Fix comment regarding the precision.
* gettext-tools/tests/format-awk-1: Add a test case with null precision.
