split: make sure hg split preserve the phase of splitting cset (issue6048)
Before this patch, while splitting we were not taking the phase
of splitting cset into account. By default new commits would
have draft changes. As we know there can two possible phases
i.e draft and secret in rewriting csets thing, so this adds
the handling of secret phase (as default is draft)
Changes in test file reflect the added behaviour.
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.
