Formatting issue when loading non standard sized seq files back to 40 columns screens

[manuelvio]

Loading non standard sized seq files into 40 columns wide screens leads to formatting issues, due to the fact that exported sequences have no information about the original row size. This is a 10x10 sample drawn in petmate: The same sample is exported in seq format and reloaded in petmate and digital paint on Vice (respectively, both 40 chars column wide):

In the case of narrower screens a solution could be adding a carriage return char (0x0D or 0x8D depending on reverse being active) at the end of each row.
