Fix garbage at end of plugin string with %h and/or %p
Commit 418cda65 from merge request !5 fixed an input buffer overrun but at the same time caused the terminating NUL byte in the output buffer to be written too late, 2 bytes per placeholder. Fix the size calculation for correctness, and use the output index and not the output length to terminate the output string. Fixes #16, reported by Stefan Thurner. [All references for Gitlab.]
