autoconf/tests/m4sh.at
Ralf Wildenhues a628e04465 * lib/m4sugar/m4sh.m4 (AS_IF): Extend to allow more than one 
test, as in `if tests; then cmd1; elif ...; else ...; fi'.
* doc/autoconf.texi (Programming in M4sh): Adjusted.
* 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.
