[PATCH, trivial, 2/3] Fix record-shape escapes in pp_write_text_as_dot_label_to_stream

[Tom de Vries]

Hi,

this patch fixes the classification of the chars '{}<> ' in 
pp_write_text_as_dot_label_to_stream. They're currently marked as 
always-escape, but that's incorrect, they should be marked as 
escape-for-record.

Bootstrapped and reg-tested on x86_64.

Will commit to stage1 trunk as trivial.

Thanks,
- Tom

	* pretty-print.c (pp_write_text_as_dot_label_to_stream): Classify chars
	'{}<> ' as escape-for-record.
