Its not necessary to (re)func_quote_for_eval in each function in the hook hierarchy. Usually it is enough if the leaf function does func_quote_for_eval and its caller just re-uses the <CALLEE>_return variable. This is follow up for the previous commit. * gl/build-aux/options-parser (func_run_hooks): Propagate $EXIT_SUCCESS return code down to caller if *any* hook succeeded. Never re-quote the result -- either the arguments are left untouched, or the options have already been properly quoted by succeeding hooks. (func_parse_options): Quote '$@' and return $EXIT_SUCCESS only if we changed something. (func_validate_options): Likewise. (func_options_prep): Likewise. (func_options_finish): New hook-caller for 'func_options' hooks. (func_options): Propagate return value down to top-level caller, but pay attention we have always set $func_options_result. * build-aux/ltmain.in (libtool_options_prep): Quote '$@' and return $EXIT_SUCCESS only if we changed something. (libtool_parse_options): Likewise. * bootstrap: Sync gl/build-aux/with option-parser. |
