Works for me...

struct flag_name would be better; will do on merge.

BTW, do we really want to bother with quoting?  Anyway, that can live
for now...

You know, _if_ we want to go that way, let's do it right; all callers
of ->show() are in seq_file.c and all of them know the previous value
of m->count.  So let's define SEQ_SKIP as 1 and teach these 3 callers
to handle it.  And make this sucker (and anything else that might want
the same kind of things) return SEQ_SKIP instead of playing with m->count
directly.

Again, will do on merge...
