Thanks for the patch!
The conventions sound reasonable, though I do not think that they are
documented in D.6 Tips for Documentation Strings section of the Elisp
manual.

The patch looks good in general, however I am not sure if it is a
good idea to change explicit 'symbol or '(...) mentions in the
documentation of the defcustoms. In particular, when 'symbol is intended
to be set as (setq variable 'symbol), I feel that 'symbol should be
preferred over `symbol' - it will make life easier for users who can
then just copy-paste the text from docstring.

Also, note that references in the babel documentation are _not_ Elisp
symbols - they are defined in #+name: name lines at the relevant src
blocks.

Finally, note that your patch does not apply after Kyle backported
similar changes from Emacs master.

Best,
Ihor
