[PATCH 0/5] More changes for sphinx-pre-install script

[Mauro Carvalho Chehab]

Hi Jon,

As asked, I changed the sphinx-pre-install script to print a different message
for the PDF minimal recommended version. This change itself was easy,
but, while testing the patch, I noticed some new weird behaviors when python
venv is used.

Basically, when using python venv, the venv environment will contain python
itself. So, an attempt to create a new virtual environment to upgrade a version
fails (at least here with Fedora 31). As I didn't notice this behavior before,
maybe the problem was due to some Fedora upgrade.

In any case, the approach I took should be generic enough to work past eventual
distro packaging differences.

At the end,  instead of a single patch, I ended needing to fix some other stuff, 
for this to work better. Oh well...

The good news is that, at the cost of a slicely more complex logic, the script
should now detect if a virtual environment works and to recommend activating
a newer environment if it exists (instead of recommending to reinstall a
venv using the name of an already-existing directory).

Mauro Carvalho Chehab (5):
  scripts: sphinx-pre-install: only ask to activate valid venvs
  scripts: sphinx-pre-install: change the warning for version < 2.4.4
  scripts: sphinx-pre-install: change recommendation text if venv exists
  scripts: sphinx-pre-install: fix a bug when using with venv
  scripts: sphinx-pre-install: change the output order
