Yes; well, there is non tgt4 in my example.  ;-)

Yep.  And except for the initial one of the two spaces before tgt1, all
whitespace can contain either spaces or tabs.

You proposed to introduce a complex perl script.  I objected that, if
we're going to introduce something complex, might as well introduce
something that more correctly parses make syntax then.  And sed, of
course, since perl is hard to read.  ;-)  Your perl script won't parse
the above example right.  automake is free to create constructs such as
the above, because every 'make' implementation *will* parse it
correctly, so it would not be a bug in automake if it created such code.
(Could be a QoI issue, but that's a different matter.)

Have I managed to completely confuse you now?  ;-)

Cheers,
