commit 62f8d5c5e2e4c5b075db68c85df1576ed19e1a9e
Author: G. Branden Robinson <address@hidden>
Date:   Sun Nov 19 22:51:29 2017 -0500

    Makefile.am: Protect args to "tr" from globbing.
    
    Prevents errors from tr during man page generation and possible
    incorrect program prefixing in those pages if, for example, some
    doofus has directories called "A", "B", ...  hanging around in
    the build tree.
