* Version 5.2.0.
+ `make check' from a build inside a chroot environment would fail
+ * tests/help-version: Specify an argument (`/') for df, in the
+ unusual event that there is no valid entry in /etc/mtab.
+ Likewise for id: add the -u option, so we don't get spurious
+ failures when there are no user or group names.
+ Patch by Tim Waugh.
+
* src/sort.c (usage) [-u]: Add punctuation so that the description in
the help2man-generated (line-joined) man page is more readable.
