For the most part I prefer to disable Emacs' fringe with
no-fringes. But I like to have the left fringe active when debugging elisp code (for the little fringe arrow pointing to the active line).
edebug-setup-hook for setting
left-only when entering edebug, but I'm fairly certain that's not what that hook is for. (Basing that on the fact that Emacs resets
edebug-setup-hook to nil all the time.)
Is there a way to set
fringe-mode back to
no-fringes upon exiting the debugger? Is there a better way to set it to
left-only upon entering?
