Eric Blake 9f4363abb6 Simplify diversion stack handling. ... * lib/m4sugar/m4sugar.m4 (m4_divert_stack): Use fewer macros, and avoid extra newlines. (m4_divert_stack_push): Compute location here, rather than caller. (m4_divert_push): Update caller. (m4_divert): Likewise, and also adjust current diversion name. (m4_divert_pop): Simplify rule that diversion stack must never go empty. (_m4_require_call): Bypass diversion stack when collecting required macro text. (m4_init): Set current diversion without requiring m4_init. * lib/m4sugar/m4sh.m4 (AS_INIT): Avoid too many pops. * lib/autotest/general.m4 (AT_INIT): Likewise. * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Schedule wrapped text to run prior to m4sugar cleanup. * doc/autoconf.texi (Text processing Macros) <m4_newline>: Mention optional argument. (Conditional constructs) <m4_ifvaln, m4_n>: Mention use of dnl. * NEWS: Undo blurb about m4_divert. * tests/m4sugar.at (m4@&t@_divert_stack): New test.
