Paul Eggert 26848af97f Simplify checks for xdg-open and xdg-email ... browse-url's xdg-open detection was too picky on some GNU/Linux desktops; see Bug#25778. Simplify the code by assuming xdg-open works if it is executable, as nowadays this is more likely to be correct than trying to use heuristics from a few years ago. Don't test for nohup: it is ineffective nowadays, as xdg-open's child uses the default action for SIGHUP even if xdg-open's invoker ignores SIGHUP. While we're at it, allow for Wayland here, as "emacs -nw" might be running in a non-X Wayland terminal. * lisp/mail/emacsbug.el (report-emacs-bug-can-use-xdg-email): * lisp/net/browse-url.el (browse-url-can-use-xdg-open): Simplify to a test for DISPLAY and whether the helper program is executable. Allow WAYLAND_DISPLAY as an option.		2017-03-09 19:02:35 -08:00
