evolve: fix createmarkers() wrapper to accept an iterable
Docstring in mercurial.obsolete says "<relations> must be an iterable of ...", and hgsubversion takes it at its word and passes a generator. Until around Mercurial 3.0, this did not cause any problems, but now it does: in a repo with both evolve and hgsubversion enabled, pushing to Subversion when obsolete changesets are present causes a crash:
[...] File "/home/gward/src/hgsubversion/hgsubversion/wrappers.py", line 346, in push obsolete.createmarkers(repo, relations) File "/home/gward/src/hg-stable/mercurial/extensions.py", line 196, in wrap return wrapper(origfn, *args, **kwargs) File "/home/gward/src/hg-evolve/hgext/evolve.py", line 332, in _createmarkers relations[idx] = (prec, sucs, meta) TypeError: 'generator' object does not support item assignment
Since hgsubersion is playing by the documented rules, evolve must be the guilty party here.
