+Subject: oop-read.h bugfixes
+
+Some years ago I contributed a feature for reading lines and records
+to liboop: oop-read.h and read.c.  Since it took a while for that
+feature to make it into distributed versions, for a long time I've
+been using my own copy of the source file.  It seems that I fixed a
+couple of bugs in my copy which are still in the Debian package.  I
+can't find any record of me having told anyone about them and now I
+find that 1.0-6 still has the bugs.
+
+There are two fixes:
+ * Initialise "rd->discard" properly
+ * Avoid rd->neednotcheck becoming negative
+
+--- a/read.c
++++ b/read.c
