I like the idea, but I have a few comments related to the patch:

1)
sprintf(mc_cl_file, "%s/.mc/%s", home_dir, XCLIPB_FILE);

Please use snprintf instead to prevent buffer overflows. If the patch is
commited as-is the long home_dir may cause overwriting of en_xcl what
causes unintentional change of functionality of your patch because
mc_cl_file is declared like: 

+static char mc_cl_file [256];
+//static FILE *fl = NULL;
+static int en_xcl = 0; /* 1 -> enable xclipboard ,  -1 -> found kde */

2)
+    //if ( start >= finish ) {
+       /* for ( ; i < finish ; i++ ) {
+           buff[i - start] = edit_get_byte (edit, i);
+       }*/
+    buff = edit_get_block (edit, start, finish, &len);
+    //}

Please avoid putting a commented out code in the patch, this only
confuses the reviewer as well as these useless hunks:

     if (!exp)

Thanks,
