IIRC there's a limited buffer used for the formatting. Also, if a dynamically created type name is 1000000 characters long I'd rather see it truncated than blow up my shell window.

I asked about this years ago, and was told it was in case the type name
pointer was bad, and to limit the amount of garbage printed. Whether
that's an actual problem or not, I can't say. It seems more likely that
you'd get a segfault, but maybe if it was pointing to reused memory it
could be useful.
