Package: python-docutils
Version: 0.8.1-4
Severity: important
File: /usr/share/emacs/site-lisp/rst.el
This is the expression for the default value of the customization
setting `rst-adornment-faces-alist':
,----
| (let ((alist '((t . font-lock-keyword-face)
| (nil . font-lock-keyword-face)))
| (i 1))
| (while (<= i rst-level-face-max)
| (nconc alist (list (cons i (intern (format "rst-level-%d-face" i)))))
| (setq i (1+ i)))
| alist)
`----
According to the elisp manual (which refers to this as "STANDARD"):
,----[ (elisp) Variable Definitions ]
| The expression STANDARD can be evaluated at various other times,
| too--whenever the customization facility needs to know OPTION's
| standard value. So be sure to use an expression which is harmless
| to evaluate at any time. We recommend avoiding backquotes in
| STANDARD, because they are not expanded when editing the value, so
| list values will appear to have the wrong structure.
`----
Unfortunately, the expression above is not safe to evaluate more than
once, because it has the side effect of modifying the very data
structure representing the expression. This happens because of the way
it passes the value of a list literal to `nconc', which destructively
modifies its arguments.
You can see the problem by customizing the variable `rst-level-face-max'
to a few different values, then asking customize to show the saved lisp
expression for `rst-adornment-faces-alist' (without having customized
that).
A quick fix would be to use a copy of the literal list, as in the
patch below.
