The regex that parses header lines potentially causes an unlimited amount of backtracking, which can cause an exception in the libc++ regex engine. The exception that occurs looks like this and is identical to the message of the exception fixed in yhirose#280: libc++abi.dylib: terminating with uncaught exception of type std::__1::regex_error: The complexity of an attempted match against a regular expression exceeded a pre-set level. This commit eliminates the problematic backtracking.
