po/LINGUAS not interpreted correctly as "whitespace separated list"

[Naohiro Aota]

doc/I18N-HOWTO gives po/LINGUAS example as follow

http://bazaar.launchpad.net/~intltool/intltool/trunk/view/head:/doc/I18N-HOWTO#L134
> Now add the add the supported languages to po/LINGUAS:

However this example won't work with current Makefile.in.in

USER_LINGUAS's code expect each line have each language code.

http://bazaar.launchpad.net/~intltool/intltool/trunk/view/head:/Makefile.in.in#L59
> USER_LINGUAS=(snip)grep \^$$lang$$ $(srcdir)/LINGUAS(snip)

Document should be fixed to list these two languages on separated line.

This is also incompatible with gettext, that accepts a "whitespace separated list". I think the correct solution would be to fix the code to be compliant with gettext and intltool documentation, rather than "restricting" po/LINGUAS format and introducing more confusion to users.
