Fix ReDoS vulnerability

In commit 87e50c6, they changed [^\[]+ → [^\[\s][^\[]*\s*. The PR description says [^\[]+ was overlapping with \s+. So they made the first char of the label exclude whitespace with [^\[\s]. But then [^\[]* (the rest of the label) still matches spaces, and \s* immediately follows it, same class of overlap.
