Subject: fmttest.c: Clear output buffer after each write.
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/1670e4d1af608291d93f02e74c57b6aef69a83ad?ds=inline

fmttest.c: Clear output buffer after each write.

Otherwise each write outputs the whole buffer again, including what's
already appeared.  Instead of the three lines 1, 2, 3, one sees 1, 1, 2,
1, 2, 3.
