evolve: store the skippedrevs in evolvestate
While doing `hg evolve`, there are some revs which are skipped as they can't be
evolved. Before this patch, we did not store this information in evolvestate and
neither they were evolved, so `hg evolve --continue` will again try to stabilize
those revisions. As much time as we run `hg evolve --continue`, this will
happen which is not a good behavior.
This patch adds a skippedrevs list to evolvestate where we store such revisions
so that we don't try to stabilize them again.
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.
