evolve: handle interrupted phase-divergence resolution gracefully
This patch adds logic to handle the interrupted phase-divergence resolution by
`hg evolve` command gracefully. We first complete the relocation of the
changeset and then do the divergence resolution. Previous functions moved
required code separate fucntions so that we can use them here.
Doc is generated with sphinx.
You can generate the doc with:
```
make
```
# Tutorials
For updating the tutorials, you need to have the docgraph extension installed
(https://pypi.python.org/pypi/hg-docgraph).
Then run the test-topic-tutorial.t and test-tutorial.t to update the output if
needed.
You'll need the dot binary (likely installed by the graphviz package in your
package manager) in order to have graphviz graphs rendered in the html output.
Simply run make in the docs directory should takes care of the conversion of
the tutorial .t files into .rst files. Then sphinx should do the rest of the
jobs by rendering graphviz graphs.
