I have a very long URL <https://www.federalregister.gov/articles/2013/09/04/2013-21140/water-quality-standards-regulatory-clarifications#p-5> in a document and it hangs way out into the right margin even though it does have a \n near the front.
My Web search turned up Andrew Moss' blog of January 4, 2013 so I put that long string in Insert -> URL rather than my usual \url{} with the url package in the preamble. Still doesn't split it across several lines. There must be a kludge I can apply to fit this in the default text width of the page, but I haven't found this so far. TIA, Rich -- Richard B.
