Hello. I've noticed that the regexp of Info-mode-font-lock-keywords
throws some false negatives and positives.
In latest Emacs, do these steps to see the bug.
1) Start Emacs: emacs -Q
2) Go to the Emacs Manual: C-h r
3) Go to the Basic node: m Basic RET
4) Go to the Inserting Text section: 1
5) Search for "which is": C-s which is RET
6) Type: M-x describe-text-properties
Notice that face is Info-quoted, even though point is not in a quote.
This is a false positive. Under the same section, there's another false
positive: "To see which characters have " is quoted too.
Now to show a false negative, in the same Emacs Manual:
Search for this string C-s ‘’’. That is: C-x 8 [ followed by C-x 8 ]
followed by C-x 8 ].
The search should get you to the Text Display section. Move point to
the middle ’, the one that is being quoted, and again type:
M-x describe-text-properties. It doesn't have the face Info-quoted,
even though it is a quote.
I hope I've described well enough the issue. Proposed patch to follow.
Best regards,
Mauro.
