* Fix bencode dictionary When parsing a bencode dictionary, the end character 'e' was never consumed. This caused a misinterpretation of the character as struct Value of an unknown type 'e'. * Fix bencode list A list was not included in the Value's parsing logic so it may have been mistakenly parsed as a string. * Fix std::ctype::isprint not including space The space character, 0x20, is considered as a printable character in ASCII and in >=C89. Adding it to the range of std::ctype::isprint also fixes other std::ctype functions that use it. * Fix bencode byte string formatting Byte strings do not render nicely in pattern data's value column if they contain non-printable characters. This commit makes the value of byte strings to be surrounded by quotation marks, and renders a warning text without quotation marks if the byte string contains non-printable characters.
