* lib/autotest/general.m4 (AT_SETUP): Only expand description once; thereafter, use its expansion, properly quoted. * tests/autotest.at (AT_CHECK_AT_TITLE): Also check macro expansion with arguments, and check for aligned output. (AT_CHECK_AT_TITLE_CHAR): Remove XFAILs for tests that now pass. Add a test for macros with parameters. * NEWS: Document the semantics change. * tests/base.at: Fix test titles containing commas. * tests/compile.at: Likewise. * tests/tools.at: Likewise. * tests/torture.at: Likewise.
