When the indents were set to longer than the width and long word breaking
was enabled, an infinite loop would result because the inner loop did not
assure that at least one character was stripped off on every pass.
add dedent() function, to remove indentation from multiline strings
(eg. triple-quoted strings). Differs from inspect.getdoc() by not
special-casing the first line (often a sensible approach for
non-docstring multiline strings). This should make this function more
general (symmetric 'indent' also possible), and more fitting for the
textwrap module.
attribute, and modify _munge_whitespace() to recognize Unicode strings
and use unicode_whitespace_trans to munge them. Still need to add a
test to make sure I've really fixed the bug.
transformed them into the initial_indent and subsequent_indent instance
attributes. Now they actually work as advertised, ie. they are
accounted for in the width of each output line. Plus you can use them
with wrap() as well as fill(), and fill() went from simple-and-broken to
trivial-and-working.
and fill() methods. Keep interface of existing wrap() and fill()
functions by going back to having them construct a new TextWrapper
instance on each call, with the preferred width passed to the
constructor.
