AC_CONFIG_FILES with ":" in a subdirectory [test]

[Kevin Ryde]

I wanted to use

        AC_CONFIG_FILES(foo/bar.h:foo/bar.in)

but found automake generates rules based on bar.h.in, not bar.in.

I think the following might be modifying @other_input_files, changing
"foo/bar.h:foo/bar.in" to just "foo/bar.h" by the time it gets to
process the foo subdirectory.

    foreach my $file (@other_input_files)
    {
        if ($file =~ /^([^:]*):(.*)$/)
        {
            # This is the ":" syntax of AC_OUTPUT.
            $file = $1;

But perl arrays and references are a mystery to me, so someone can
check that.

In any case with it fixed the right rules are generated for bar.h, but
DIST_COMMON seems to get foo/bar.in, whereas I think it should be just
bar.in.  Perhaps the following a few lines later needs some sort of
basename.

        &push_dist_common (@inputs);

colon7.test gets these problems, the couple of greps below will let it
detect them.

        * tests/colon7.test: Grep for a couple of AC_OUTPUT problems.
