Thanks for the report. The regression came at commit b07a2b3d, when I swapped to a more efficient whitespace mapping operator, and nothing in the testsuite exercises it (yet). I'm still playing with it, but I'm hoping that I can do a cleanup pass that recognizes any whitespace inside extra [ ] during _m4_split, and skip replacing just those instances. http://git.savannah.gnu.org/cgit/autoconf.git/commit/?id=b07a2b3d > if there is no white space between the [], then things actually work and the > output is what people expect: > AC_INIT > AC_ARG_VAR(VAR, [[cow-moo] desc]) > AC_OUTPUT > $ autoconf && ./configure --help | grep cow-moo > VAR [cow-moo] desc Correct, as is the use of quadrigraphs instead of raw [ and ]. - -- Don't work too hard, make some time for fun as well!
