[Toybox] [PATCH 1/2] sh: implement \dD{}tT at AuvVW prompt control characters

[Aleksander Morgado]

Hey

> Currently about a quarter of Bash's prompt control characters are supported, this patch brings it up to about 70%

+          } else {
+            fmt = strncpy(xmalloc(end-prompt), prompt, end-prompt);
+            fmt[end-prompt] = '\0';
+            prompt = end+1;
+          }

Isn't  fmt[end-prompt] = '\0'; writing past the allocated buffer?
