annotate xrogue/outside.c @ 222:a666e4a034ed

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix curses library detection. A custom autoconf macro searched for the curses library, and provided an option to use ncurses instead of a (presumably deficient) curses implementation. Unfortunately, some of the Makefiles ignored the search's results. Now that this is fixed, building against pdcurses should be easier too.
