Log message:
fix some whitespace, mostly introduced in the previous
python 3.4 / 3.5 removal commit.

Log message:
Omit mentions of python 34 and 35, after those were removed.

- Includes some whitespace changes, to be handled in a separate commit.

Log message:
PKGREVISION bump for anything using python without a PYPKGPREFIX.

This is a semi-manual PKGREVISION bump.

Log message:
*: Move SUBST_STAGE from post-patch to pre-configure

Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.

Log message:
extend PYTHON_VERSIONS_ for Python 3.7

Log message:
games/*: fix alignment of variable values

pkglint -Wall -r --autofix --only aligned

After running the above command, three packages had to be adjusted
manually:

In maelstrom-x11, pkglint didn't see that a commented variable
assignment should have been re-aligned as well.

In netmaze, there was a single line that didn't align well with all the
others, but pkglint decided to adjust the whole paragraph to this single
line. The result would have been ok, but not good.

In tscp, there was a paragraph where some of the lines were indented
one space more than the others. This rule is useful when one variable
name is very long compared to the others, but not in this case.

Log message:
Add python-3.6 to incompatible versions.
