ctl.c fix handling of interrupted edits fix handling of <ctrl> + <c> interruption that previously caused lock files to remain and prevent further editing The default SIGINT handler does the wrong thing when a file is currently locked for editing. Please try the diff below. ensure that edited files get unlocked if the user types Ctrl-C at prompt While editing files, temporarily disable the default SIGINT handler which does a long jump to displaying a command prompt. Otherwise we would jump away without removing our lock on the file and future attempts to edit the file would fail. Issue found by Tom Smyth. Fixed by stsp@ Thanks
