+       * src/nice.c (GET_NICE_VALUE): Renamed from GET_PRIORITY.
+       All uses changed.
+       (NZERO): New macro, if system doesn't define it already.
+       (usage): Distinguish priorities from nice values.
+       Don't assume NZERO is 20.
+       (main): Use bool instead of int where appropriate.
+       If user specifies an adjustment out of range, always truncate it
+       to an inrange value instead of sometimes giving an error message
+       and sometimes not.
+       Do not assume that -1 is an error return from "nice" or
+       "getpriority", as it might be the current nice value minus NZERO.
+       If nice/setpriority fails with errno == EPERM, go ahead and run
+       the command anyway; POSIX requires this.
+
        * src/pathchk.c: Include euidaccess.h.
        (dir_ok): Use euidaccess, not access.
        * src/test.c (R_OK, W_OK, X_OK, FOK): Remove; system.h defines them.
