What
Every [gateway] line written to stderr now passes through an escaper that converts newlines, carriage returns, tabs, C0 and C1 controls and line separators into \n, \r, \t or \uXXXX, so text coming from a request cannot forge extra log lines.
Evidence
lxH = { "\n": "\\n", "\r": "\\r", "\t": "\\t" };
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
