Thanks.  (Is this in a document somewhere?  I'm afraid I couldn't get
the climacs-internals texi to build, probably because I hadn't chased
down enough dependencies for fig2whatever)

... oh, yes, you can request a different (unobtainable!) cache value.
Devious.

(Relatedly...) I knew there was something else I wanted to ask, but I
forgot about it.  I couldn't see if or how the display of the buffer
contents in the textual-view (that is, in normal climacs operation)
was to be extended -- for instance for fontifying syntactic markers.
It would be nice if I could fontify syntactically incorrect or
incomplete tabwords, for instance -- my parser is propagating that
information to the syntax, in the form of distinct END and AFTER marks
-- but I couldn't see any neat way of hooking into the display code.
Am I simply the first to need this?  (I seem to recall in the mists of
time there being a texinfo mode, but maybe that got zapped somewhere
along the line?)

Cheers,

Christophe
