New description:
Add 3 methods to `sage/combinat/words/finite_word.py`:
1. sturmian_desubstitute_as_possible
1. is_sturmian_factor
1. is_tangent
Add a protecting `is_tangent` method to `sage/combinat/words/paths.py`.
{{{
sage: w = Word('01110110110111011101',alphabet='01')
sage: w.is_tangent()
True
}}}
Depends on #8739.
