Use put-text-property to add a face to some text using the `face' property.
Prevent subsequent "erasure" of that highlighting by font-lock.
I would like to be able to, say, set a particular text property on the same
text, which would cause font-lock to ignore that text (skip over it, as if
it weren't there).
I thought that's what property `fontified' (= t) would do, but that seems
not to be the case. The Elisp manual says this about `fontified':
This property says whether the character has a face assigned to it
by font locking. The display engine tests it to decide whether a
buffer portion needs refontifying before display. *Note Auto
Faces::. It takes one of three values:
`nil'
Font locking is disabled, or the character's `face' property,
if any, is invalid.
`defer'
This value is only used when "just in time" font locking is
enabled and it means that the character's `face' property is
invalid and needs deferred fontification.
`t'
The character's `face' property, or absence of one, is valid.
