Comment:
Hi,
The patch applies well, the doc builds fine, the tests pass and the
previous comments have been taken into account.
This is a very nice and useful patch, thank you.
You could add an example of a morphism without fixed points but with
periodic points, for example:
{{{
sage: f = WordMorphism('a->b,b->c,c->ab')
sage: f.fixed_points()
[]
sage: f.periodic_points()
[[word: abbcbccabbccabcababbcbccabcababbccababbc..., word:
bccabcababbccababbcabbcbccabcababbcabbcb..., word:
cababbcabbcbccababbcbccabbccabcababbcabb...]]
}}}
