bug#3282: 23.0.93; (display-supports-face-attributes-p (list :underline t)) returns nil on tty

[Yoshiaki Kasahara]

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-bug@gnu.org mailing list.

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

After I updated Emacs from 23.0.91 to 23.0.93, 'underline' face became
bold on tty, instead of underlined.  Still I can make 'underline' face
underlined by customize-face manually after Emacs started.

After some investigation, I noticed that
(display-supports-face-attributes-p (list :underline t)) returns nil
on tty now. Previously it returned t in emacs-23.0.91 on tty. There is
no such problem on X frames.

Actually (display-supports-face-attributes-p (list :weight "bold"))
also returns nil on tty, so something is totally broken for tty.

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/local/share/emacs/23.0.93/etc/DEBUG for instructions.
