bug#26673: 25.2; window-combination-limit customize/docstring mismatch

[Allen Li]

There seems to be a mismatch between the documentation string and
customize widgets for ‘window-combination-limit’.

The documentation string (from ‘describe-variable’) reports the valid
values as:

  nil
  ‘window-size’
  ‘temp-buffer’
  ‘display-buffer’
  t

‘window-combination-limit’ evaluates to ‘window-size’, which I presume
is the default value.

The customize interface presents a Value Menu with the choices:

  nil
  temp-buffer-resize
  temp-buffer
  display-buffer
  t

The customize interface reports the current value as t, despite
‘window-combination-limit’ evaluating to ‘window-size’.
