That was not necessary before. %-/
Removed existence check from corner_check() routine (obsolete).
Added code to generate required shapes which were not specified by the user
Clean-up in shape_def rule (use freeshape() and some more)

1999/07/21 18:53:17; boxes.c 1.27 (tsjensen)
Bugfix: Empty box sides were still counted when -s was specified (so
-s x5 would get you only three lines).

1999/07/21 18:50:48; generate.c 1.4 (tsjensen)
Added GNU GPL disclaimer
Bugfix: When doing the line justification in output_box(), the padding was counted as part of the modifyable inner part of the box instead of the fixed box itself, which resulted in strange bugs (tricky one).
