Embedded )s(?) confuse the highlighter, trailing ) highlighted red

Consider the following snippet (part of dash):

AC_ARG_ENABLE(test-workaround, AS_HELP_STRING(--enable-test-workaround, \
	[Guard against faccessat(2) that tells root all files are executable]),,
	[enable_test_workaround=auto])

This is correct and uses all-upstream-autoconf macros. However, it highlights as such:

Cf. also:

AC_LINK_IFELSE([AC_LANG_PROGRAM([void t() {}
                                 void a() __attribute__((__alias__("t")));],
                                [a();])],
               [dash_cv_have_attribute_alias=yes])

I'm not sure if ignoring the parentheses inside the bracketed argument to AS_HELP_STRING would be technically correct or not. What if you preceded it with m4_define([faccessat], [...])? But regardless, the current result, with an unbalanced bracket in the enclosing macro, seems incorrect. I'd welcome a pull request to fix this.

The following code might have the same problem:

AC_DEFUN([FUNC],[
  AC_SUBST([XXX],[YYY])
])
