* call-seq:
* blob.text(max_lines = -1, encoding = Encoding.default_external) -> String
*
* Return up to +max_lines+ of text from a blob as a +String+.
*
* In Ruby 1.9.x, the string is created with the given +encoding+,
* defaulting to Encoding.default_external.
*
* In previous versions, the +encoding+ argument is dummy and has no
* effect on the returned string.
*
* When limiting the size of the text with +max_lines+, the string is
* expected to have an ASCII-compatible encoding, and is checked
* for the newline +\n+ character.
