Subject: python-format: Accept null precision.
X-Git-Tag: v0.26~79
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b6ea1c2cbe405f78f53fae0ae39b7baecf1cb332;p=thirdparty%2Fgettext.git

python-format: Accept null precision.

Proof that it's valid:
$ python
print("%(value).f" % { 'value': 3.1415926535 })

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