I'm not convinced we should assume that much.
PostgreSQL docs could as well be in /var/www/postgresql-doc/8.0.0 ...

Really? Please show me... I read:

----8<------------------------------------------------------

install: html/postgis.html man/shp2pgsql.1 man/pgsql2shp.1
        @mkdir -p $(DESTDIR)$(docdir)/postgis
        @mkdir -p $(DESTDIR)$(mandir)/man1
        $(INSTALL_DATA) html/postgis.html $(DESTDIR)$(docdir)/postgis/postgis.html
        $(INSTALL_DATA) ../README.postgis $(DESTDIR)$(docdir)/postgis/README.postgis
        $(INSTALL_DATA) man/pgsql2shp.1 $(DESTDIR)$(mandir)/man1/pgsql2shp.1
        $(INSTALL_DATA) man/shp2pgsql.1 $(DESTDIR)$(mandir)/man1/shp2pgsql.1

uninstall:
        rm -f $(DESTDIR)$(docdir)/postgis/postgis.html
        rm -f $(DESTDIR)$(docdir)/postgis/README.postgis
        rm -f $(DESTDIR)$(mandir)/man1/shp2pgsql.1
        rm -f $(DESTDIR)$(mandir)/man1/pgsql2shp.1

This would be an attempt of making the piggy-backing approach
reflect old postgis layout, is it different from 1.0.x ?

Basically I think postgis should use its own layout (this is
what happen when using --prefix). Omitting --prefix uses
the old layout (the piggy-backing one used in pre 1.1).
In any case specific flags would override path.

So, any piggy-backing related path should be fixed to
old layout (rather then changing between 1.0 and 1.1).
Any inconsistency between install/uninstall should be fixed.
New layout strategies should be discussed for use in the
default --prefix case (like, should postgis/ be appended to
docdir and datadir?).
