Re: Preserving trailing whitespace?

[Lloyd Zusman <ljz@xxxxxxxxxx>]

I found out why this happens.  I found this in src/cmds.c ...

  /*{{{ eol_cmd */
  int eol_cmd (void)
  {
     eol();
     if ((0 == (CBuf->flags & READ_ONLY))
  #if JED_HAS_LINE_ATTRIBUTES
         && (0 == (CLine->flags & JED_LINE_IS_READONLY))
  #endif
         )
       jed_trim_whitespace();
     return(1);
  }

Is there any way to change this so that the call of
jed_trim_whitespace() can be conditionally disabled in eol_cmd?
