And does everybody agree that this is a desirable change?
As for the patch itself, you could replace all this:
+ /*
+ * Take into account any title present in the user setup as a part of
+ * what is printed for each iteration by using it as a header.
+ */
+ if (myopt.title)
+ {
+ title_len = strlen(myopt.title);
+ title = pg_malloc(title_len + 50);
+ head_title = pg_strdup(myopt.title);
+ }
+ else
+ {
+ title_len = 0;
+ title = pg_malloc(50);
+ head_title = pg_strdup("");
+ }
...with:
head_title = pg_strdup(myopt.title != NULL ? myopt.title : "");
title_len = strlen(head_title);
title = pg_malloc(title_len + 50);
Better yet, include the + 50 in title_len, and then you don't need to
reference the number 50 again further down.
