I suggest patching src/Darcs/Utils.lhs to implement "view_file" on top
of get_viewer, similar to how get_editor and edit_file behave.  It's
extremely sensible to try running more, then cat, if less can't be
executed -- even on Unix.

| edit_file :: String -> IO ExitCode
| edit_file f = do
|   ed <- get_editor
|   exec_interactive ed f
|              `ortryrunning` exec_interactive "emacs" f
|              `ortryrunning` exec_interactive "emacs -nw" f
|              `ortryrunning` exec_interactive "nano" f
| #ifdef WIN32
|              `ortryrunning` exec_interactive "edit" f
| #endif
| get_editor :: IO String
| get_editor = getEnv "DARCS_EDITOR" `catchall`
|              getEnv "DARCSEDITOR" `catchall`
|              getEnv "VISUAL" `catchall`
|              getEnv "EDITOR" `catchall` return "vi"
|
| get_viewer :: IO String
| get_viewer = getEnv "DARCS_PAGER" `catchall`
|              getEnv "PAGER" `catchall` return "less"
