stripSpace :: Text -> Text

A (quite possibly inefficient) re-implementation of git stripspace. This function normalizes a Text buffer to conform to the following rules:

• All trailing white space is stripped.
• Empty lines at the beginning or at the end of the buffer are stripped.
• Consecutive empty lines between paragraphs are collapsed into one.
• \r\n line endings are normalized into \n.
• If the buffer is not empty, then its last line is terminated by \n.
• If the buffer is empty (i.e. it contains only white space), then it comes out as the empty string.
