tests: fix PYTHONPATH manipulation on Windows
Without the semicolon separator and quotes, the variables ends up like this:
c:\Users\Matt\projects\hg-evolve:c:\Users\Matt\projects\hg-evolve:
c:\Users\Matt\projects\hg;c:\Users\Matt\projects\hg-evolve\tests;
c:\Users\Matt\projects\hg\tests
That in turn makes the local evolve code unreachable, and the system installed
code is tested instead.
I'm testing against `uname` instead of a trivial python script printing os.name
because maybe one day tests will run on WSL.
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.
