":version" entries in defcustoms

[Reiner Steib <4.uce.03.r.s@nurfuerspam.de>]

Hi,

I went through lisp/ChangeLog.2[1] (in the v5-10 branch) and added
`:version "21.4"' entries to most/all new defcustoms.  "all" might be
too optimistic: I did `M-x occur RET new.*variable RET' which should
cover most new variables.

I don't know what to do with libraries as pgg*.el.  Should we add
`:version "21.4"' to all defcustoms there?

Adding the custom version later (like I did) is annoying.  How can we
simplify this in the future?  The problem is that we don't know the
correct Emacs version number (which Emacs will contain this version of
Gnus) to add when adding a variable in Gnus.

Bye, Reiner.

[1] lisp/ChangeLog.2 now contains changes upto the release of 5.10.6.
    It probably starts from Oort, but I'm not sure about this.

[2] "all" might be too optimistic: I did `M-x occur RET new.*variable
    RET' which should cover most new variables.
