[Message part 4 (text/plain, inline)]

Preparing for a release, I noticed a build failure. Here's what I've
just pushed, along with a few maintenance-related diffs:

* src/diff.c (usage): Assert that each line length is no longer than
the minimum required size of 4095.  This lets newer gcc (currently
9.0.0 20181219) infer that it need not issue this warning:
diff.c:1012:19: error: '%.*s' directive output between 0 and 2147483647
bytes may exceed minimum required size of 4095
[-Werror=format-overflow=]
1012 |        printf ("  %.*s", msglen, msg);
