AC_SUBST_FILE invocations. Fix test to actually verify the
AC_CONFIG_FILES output.

test, as in `if tests; then cmd1; elif ...; else ...; fi'.

* tests/m4sh.at (AS_IF and AS_CASE): Test this. Also make sure
both macros are defun'ed so that required macros are evaluated
outside.
document m4_for, m4_foreach, m4_foreach_w, and mention
obsolete AC_FOREACH.
(Obsolete Macros): Document AC_FOREACH.
* lib/m4sugar/m4sugar.m4 (_m4_for): Fix declaration comment.
(m4_for): Fix to never loop (almost) endlessly, work correctly
with arithmetic expressions in arguments, a step of zero or
non-integer multiple of the interval, and avoid integer
overflow.

m4_foreach_w.

AS_SHELL_SANITIZE.
Be consistent about spaces after commas.
Insert [] where empty args look a bit funny.
Fix some "i.e." and "e.g." usages.
Try to avoid "X/Y" usages.
Don't be pedantic about "ISO C99"; just say C99.

* tests/tools.at (autoupdating AU_ALIAS): New test for AU_ALIAS
`$#' bug.
(autoupdate): Updated to match AU_ALIAS fix.
(_AC_FC_MAIN, __AC_FC_NAME_MANGLING): Use _AC_LANG in check
messages to differentiate Fortran and Fortran 77 tests.
(AC_FC_SRCEXT, AC_FC_FREEFORM): Use AC_LANG_PUSH/POP instead of
AC_LANG_ASSERT, to allow use in mixed-language projects.
