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 emacs-pretest-...@gnu.org mailing
list.

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

Start Emacs 23 with the -Q option (using MS Windows Vista).
Open a customization buffer for the variable printer-name.
Click on the Value Menu button and select Name.
The whole line after Name: AND THE NEXT LINE turn grey.
Enter the name printer.
Click the State button and select Set for Current Session.
Use C-x v to display the value of the variable printer-name. It shows:

printer-name is a variable defined in `lpr.el'.
Its value is
"printer\n   State: EDITED, shown value does not take effect until you set
or save it."

Customize is picking up the line below the input line in the customize
buffer as part of the input at the time when the customization is saved.

I looked at a few other variables with similar custom specifications,
but I can't find any others that show the same bug.

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
c:/NTEmacs/emacs-23.0.93/etc/DEBUG for instructions.
