evolve: strip the extra obsmarkers if any on `hg evolve --abort`
Previous patches started storing some obsmarkers which needs to stripped during
`evolve --abort` which can't be stripped by stripping the new evolved changesets
because they point to a node which existed before the evolution was performed.
This patch adds logic to strip those obsmarkers by finding their indices in the
obsstore and then stripping them.
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.
