    Reland "[regexp] Correctly escape a backslash-newline sequence" · eea168f8
    Jakob Gruber authored
    This is a reland of 7d1f95d6
    
    The reland fixes a performance issue in that we incorrectly marked
    every pattern containing a backslash as needing to be escaped,
    resulting in a new string allocation instead of reusing the existing
    string.
    
    Original change's description:
    > [regexp] Correctly escape a backslash-newline sequence
    >
    > When printing the source string, a backslash-newline sequence ('\\\n',
    > '\\\r', '\\\u2028', '\\\u2029') should be formatted as '\n', '\r',
    > '\u2028', '\u2029', respectively. Prior to this CL it was formatted as
    > a backslash followed by the literal newline character.
