[GUILT v2 24/29] disp no longer processes backslashes.

[Per Cederqvist <cederp@opera.com>]

Only one invocation of "disp" or "_disp" actually needed backslash
processing.  In quite a few instances, it was wrong to do backslash
processing, as the message contained data derived from the user.

Created the new function "disp_e" that should be used when backslash
processing is required, and changed "disp" and "_disp" to use printf
code %s instead of "%b".
