#include "config.h"
Read exactly one line and strip the trailing newline if any. If the
file was on EOF, return NULL. Otherwise, return all the data in a
dynamically allocated buffer.
+
+ If line is non-NULL, it will be used as an initial buffer, to avoid
+ unnecessary mallocing each time this function is called. If buf is
+ given, and buf needs to be expanded, the var pointed to by buflen
+ will be increased.
