Subject: [PATCH] d.legend.vect: Initialize title size (#3095)

Later test (line 270) uses title width to compute background size regardless of title presence, but original code initialized title_w only when title was set.

This fixes occasional extra wide legend background rectangle.

Identified by valgrind as: Conditional jump or move depends on uninitialized value(s).
