// The "Fastest" cases don't count line numbers and, therefore, don't need
// to be sensitive to line feeds. "ViewSource" and "LineCol" count line
// numbers and, therefore, care about line feeds.
//
// Even the "Fastest" case needs to care about carriage returns in order
// to be able to normalize CR and CRLF to an LF. (CRLF to LF ends up
// finding the LF without SIMD once the CR has been detected using SIMD.)
//
// The three boolean arguments and their defaults are:
// bool aAllowSurrogates = true,
// bool aAllowHyphen = true,
// bool aAllowRightSquareBracket = true,
//
// Parsing from network (the `LineCol` cases) sets aAllowSurrogates
// to false in order to count column numbers by scalar values instead
// of UTF-16 code unit.
//
// The hyphen and the right square bracket share the low 4 bits (0xD)
// with the carriage return, so they need to be special-cased and can't
// be covered byt the lookup table that's used for other characters
// of interest, since the lookup table already needs to contain CR.
