I suspect that this indicates c-mode being too dumb to use linear-time
indent algorithm. 20 years ago it was acceptable to have
quadratic-time indent logic; one could not do better, since
parse-partial-sexp was not designed well enough. But I added
necessary hooks to parse-partial-sexp (more than?) 10 years ago.
Nowadays all the decent modes should have linear-time logic for
indent. It looks like c-mode is not decent enough...
Puzzled,
Ilya
