getline.3: Remove unneeded check before free()
The manpage of getline shows an example with an extra NULL pointer check before it calls free. This is unneeded according to free(3): If ptr is NULL, no operation is performed. This patch removes the "if" check. See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572508 Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>
