Multi-line output variables appear incorrectly in config.log

[Daniel Richard G.]

I am using Autoconf 2.68, and just recently began to take advantage of
its support for multi-line substitutions. Unfortunately, I came across
one minor bug related to this.

If I have e.g.

        multiline_var='zero
         one
        !two
        "three'

        AC_SUBST([multiline_var])

then in config.log, I see

        ## ----------------- ##
        ## Output variables. ##
        ## ----------------- ##

         one
        !two
        "three'
        DEFS='-DPACKAGE_NAME=\"AutoconfBug\" -DPACKAGE_[...]
        ECHO_C=''
        ECHO_N='-n'
        ECHO_T=''
        [...]
        multiline_var='zero

I am attaching a tarball containing a minimal test case along the
above lines.
