evolve: use stack alias s# in `hg evolve` msgs
As repository grows revision number lose their usefulness. To
make it a little better than now, after this patch we will be
using short stack aliases introduced by the topic extension
(as displayed by `hg stack`).
These stack aliases s# will be used only when user has enabled
topic extension and his repo's current active topic is same as
the revs to be evolved.
For now, this patch doesn't cover `continue` case. I will discuss about this
with Pierre-Yves David. Maybe we have to store the info in evolvestate that "we
were using stack aliases".
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.
