Normally all embedded newlines are escaped, however there are
three exceptions:
{,
} and
~. The first two are intended
cover nested explanations, see function and attribute explanations
for examples (.visit_Call(), visit_Attribute()). The last one is
for when one explanation needs to span multiple lines, e.g. when
displaying diffs.

This will return a list of lines split on '

Any other newlines will be escaped and appear in the line as the

Format the individual lines
This will replace the '{', '}' and '~' characters of our mini
formatting language with the proper 'where ...', 'and ...' and ' +
...' text, taking care of indentation along the way.
Return a list of formatted lines.

Unless --verbose is used this will skip leading and trailing
characters which are identical to keep the diff minimal.
If the input are bytes they will be safely converted to text.
