[PATCH 0/1] Fix -Wformat-overflow= warnings in zftp.c

[Wesley Schwengle <wesleyschwengle@gmail.com>]

Hello all,

I was compiling zsh from master on my Debian testing box with cc 8.3.0
and I got the following warning:

zftp.c: In function ‘zfstats’:
zftp.c:1265:26: warning: ‘%02d’ directive writing between 2 and 11 bytes
into a region of size between 9 and 16 [-Wformat-overflow=]
sprintf(tmbuf, "%04d%02d%02d%02d%02d%02d",
^~~~
zftp.c:1265:21: note: directive argument in the range [-2147483647, 2147483647]
sprintf(tmbuf, "%04d%02d%02d%02d%02d%02d",
^~~~~~~~~~~~~~~~~~~~~~~~~~
zftp.c:1265:6: note: ‘sprintf’ output between 15 and 67 bytes into a
destination of size 20
sprintf(tmbuf, "%04d%02d%02d%02d%02d%02d",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
tm->tm_year + 1900, tm->tm_mon+1, tm->tm_mday,
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
tm->tm_hour, tm->tm_min, tm->tm_sec);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I made a small patch that resolves the warning.

Cheers,
Wesley
