[jed-users] ignoring non-files on command line

[Ulli Horlacher <framstag@xxxxxxxxxxxxxxxxxxxx>]

I often edit more than one file with jed.
Typically I call something like: jed x*

But if one of these x* files is not a regular file (directory, fifo, etc),
I get the error message:

File /export/home/framstag/xbin not readable.

and jed has an empty buffer associated with that file (directory) which is
NOT what I want!

My solution: I copied the function command_line_hook() from site.sl to
defaults.sl and substituted:

          {
             flush ("Reading " + file);
             () = find_file(patch_cmdline_file (file));  ++n; --i;
          }

with:

	  {
             if (is_file(file)) {
               file = expand_symlink(file); 
	       flush("Reading " + file);
	       () = find_file(patch_cmdline_file(file));
             } else {
	       flush(file + " is not a regular file, skipping");
             }
             ++n; --i;
	  }


Now jed only loads regular files on the command line.
