[AUCTeX] Faces change after disabling a ligature with "|

[Marcus Frings]

Hello,

today I upgraded from 11.85 to 11.86 as Debian finally put your latest
version into their archive.

If I disable a ligature with "| in a word the rest of the buffer gets
the wrong fontification because the face changes to
font-latex-verbatim-face as can be seen in the following screenshot:

http://imagebin.org/112008

If I downgrade to 11.85 this behaviour does not occur and also if I
remove "| from the word (while using 11.86), the face changes to the
normal one again.

Is this is a bug or is there anything I am doing wrong?

Regards,
Marcus
