Subject: Remove sbr/peekc.c containing unused peekc().
X-Git-Url: https://diplodocus.org/git/nmh/commitdiff_plain/f7045eaebc7cd9a7b2d4a29c355a153887b9921c?hp=87e0228a43ba73eac409f2f0d7f75f3b6148adfc

Remove sbr/peekc.c containing unused peekc().

gcov showed it wasn't getting any;  we've all been there.
It didn't check for EOF, nor that the ungetc(3) succeeded.
