Subject: bug#34027: 27.0.50; disable-theme resets variables to their initial values
Date: Thu, 10 Jan 2019 13:25:17 +0100

Scenario:

- Declare a variable (either defvar or defcustom)
- Change the initial value to something else
- Enable a theme, which changes the value to something different, again
- Disable the theme

I would expect that the variable has been reset to the value prior
enabling the theme. But it is reset to the initial value.

The documentation of disable-theme isn't helpful, it just says "Disable
all variable and face settings defined by THEME."

I've added the test case custom--test-theme-variables in
test/lisp/custom-resources/custom--test-theme.el for showing the effect.
