[bug #30381] Don't avoid implicit rule recursion quite so soon.

[Paul D. Smith]

Follow-up Comment #2, bug #30381 (project make):

Actually my example is solved by your suggestion to use a stack of targets. 
However, if you imagine a pattern rule where every iteration of the rule
_grows_, instead of shrinks, then a stack of targets wouldn't help.  What
about:

%.x : %.x.x ; cat $< > $@


In this case every time we iterate we have a new target.

A maximum recursion would solve it.  I'm not sure how difficult it would be
to implement though, and I'm not sure we have a strong use-case for it.  If
you can define the number of iterations then it should be possible to define
targets in your makefile to "fix" the problem... no?
