Avoid extra side effects in m4sugar list expansion.
* lib/m4sugar/m4sugar.m4 (m4_mapall_sep, m4_list_cmp): Wrap
around...
(_m4_mapall_sep, _m4_list_cmp_raw): ...new helpers, to avoid
duplicate side effects.
(m4_version_compare): Adjust caller.
* lib/m4sugar/foreach.m4 (m4_list_cmp): Rename...
(_m4_list_cmp_raw): ...to match m4sugar.
* doc/autoconf.texi (Looping constructs): Document the behavior of
side effects.
* tests/m4sugar.at (M4 loops, m4@&t@_map, m4@&t@_version_compare):
Ensure only one side effect.
(recursion): Fix test typo.
