[PATCH, trivial, 1/3] Simplify loop in pp_write_text_as_dot_label_to_stream

[Tom de Vries]

Hi,

this patch simplifies the loop structure in 
pp_write_text_as_dot_label_to_stream:
- it rewrites the while loop into a for loop
- it factors common code out of the switch cases.

No functional changes.

Bootstrapped and reg-tested on x86_64.

Will commit to stage1 trunk as trivial.

Thanks,
- Tom
