bug#4459: 23.1; ERC customize does not hide password from view

[Robin Green]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

If I use the Customize mode to set a password for ERC to try automatically, Customize does not hide the password from view. (Incidentally, I can't hide the password from view by clicking the relevant show/hide arrow afterwards, either - it refuses to hide anything.)

To reproduce this, in ERC major mode (reachable with M-x erc), choose Customize from the ERC menu. Then choose the Erc Services group. Then, under "Erc Nickserv Passwords:", press the INS button and choose some Network name. Press the INS buton under "Nickname and password:" and enter some arbitrary nickname and password. The password is visible on the screen (unlike when ERC prompts for a password itself, when it hides the password by printing periods instead of the actual password characters).

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/23.1/etc/DEBUG for instructions.

I'm afraid this is not really feasible to fix, because of the way
Customize is designed.

Would it make sense for me to turn this variable into a defvar instead
of a defcustom, so that users can't accidentally set it in their emacs
init file?
