Subject: [PATCH] Remove the ambiguity from the PostScript number regex

`\d+\.?\d*` can split a run of digits in as many ways as it is long, so
it would backtrack polynomially if anything following it could reject.
The optional exponent can't, hence no bug today, but `\d+(?:\.\d*)?`
accepts the same numbers unambiguously.
