Bug: configure parameters ignored

[Moritz Schmitt]

I'm the FreeBSD port maintainer for GNU indent. It seems that at least
the following parameters of the configure script are ignored:

        --docdir
        --dvidir
        --psdir
        --pdfdir
        --htmldir

I know next to nothing about autotools (and have currently no
inclination to read up on it) but it seems to me that the lines

        docdir = $(prefix)/doc/@PACKAGE@
        dvidir = $(docdir)
        psdir = $(docdir)
        pdfdir = $(docdir)
        htmldir = $(docdir)

in doc/Makefile.in should read

        docdir = @docdir@
        dvidir = @dvidir@
        psdir =  @psdir@
        pdfdir = @pdfdir@
        htmldir = @htmldir@

How one gets automake to do this, I don't really know. It probably has
to do with the corresponding entries in doc/Makefile.am. But you guys
will know better how to fix this.
