man.hyphenate.urls boolean man.hyphenate.urls Hyphenate URLs? 0 If zero (the default), hyphenation is suppressed for output of the ulink url attribute. If hyphenation is already turned off globally (that is, if man.hyphenate is zero, setting man.hyphenate.urls is not necessary. If man.hyphenate.urls is non-zero, URLs will not be treated specially and are subject to hyphenation just like other words. If you are thinking about setting a non-zero value for man.hyphenate.urls in order to make long URLs break across lines, you'd probably be better off experimenting with setting the man.break.after.slash parameter first. That will cause long URLs to be broken after slashes.
