IMO, using the same convention everywhere for a task name (i.e. using quotes)
and the same convention as thread name is a nice thing to have.
That e.g. gives the below, where thread and task names have now the same
representation.

(gdb) info threads
  Id   Target Id                                       Frame

(gdb)

This is IMO worth having the "if" on is_mi_like_p.
The code can be made somewhat cleaner like the below:

+      /* Finally, print the task name, without quotes for mi like.  */
+      {
+       const char *opt_quote = (uiout->is_mi_like_p () ? "" : "\"");
+
+       uiout->field_fmt ("name",
+                         "%s%s%s",
+                         opt_quote,
+                         task_info->name[0] != '\0' ? task_info->name
+                         : _("<no name>"),
+                         opt_quote);
+      }


I have fixed the other comments.

Thanks for the review,
