python.el and others.

While working at a general-close mode, tests succeeded locally, but 
Travis CI repeatedly sent errors like this:

FAILED gen-close-python-doublequoted-tqs-test
FAILED gen-close-python-singlequoted-tqs-test

for example from
https://travis-ci.org/emacs-berlin/general-close/builds/68578148

These tests succeed, if boolean gen-verbose-p was set to t, which OTOH 
isn't intendet at batch-mode.

Both macros in question -- for example gen-test-with-python-buffer-- 
have this:

   `(when gen-verbose-p
 (switch-to-buffer (current-buffer))
 (font-lock-fontify-buffer))`

AFAICS the error is caused, because TQS-syntax in python.el is set by 
syntax-propertize-function

Documentation:
Mode-specific function to apply syntax-table' text properties. It is the 
work horse ofsyntax-propertize', which is called by things like
Font-Lock and indentation.


Setting up syntax seems to require font-lock - which doesn't feel right.

Don't do that, then.

Call (syntax-propertize (point-max)) instead.

That only says that font-lock requires it, not vice versa. The docstring 
even mentions `syntax-propertize'.
