Minor nit for future patches: git-log _really_ wants a one-line description of the patch, separated by a blank line, before the rest of the commit description. That's why I've been starting to add a summary line to all my ChangeLog entries, then reusing that summary line (plus one more newline) in my git commit. For an example, this is 'git-log -4 --pretty=oneline' after my latest push: 987a33376699a92cb00962aedd4632d05bc7cef6 Another round of regex avoidance. 1a128bd6e62856ce29d98848a6d424d9f4f9715e Whitespace cleanup. 9174b63f95aaf58680bda01f1746dc6f44860a59 * lib/m4sugar/m4sugar.m4 (m4_shift2, m4_shift3): New macros. (m4_shiftn): Remove no-longer-needed optimization. Perhaps we should remove m4_shiftn entirely? (m4_case, b4_bmatch, m4_map_sep, m4_bpatsubsts, m4_join): Prefer m4_shift2 and m4_shift3 to m4_shiftn. * lib/autoconf/lang.m4 (_AC_LANG_DISPATCH): Likewise. * lib/m4sugar/m4sh.m4 (AS_CASE, AS_IF): Likewise. * tests/autotest.at (AT_CHECK_AT_TEST): Likewise. 7b96e241f7c2eeae31b69ef6d64c20943ad2f599 Comment touchups. -- Eric Blake
