Subject: [PATCH] code-style: use constant length array (#79)

currently the code-base doesn't make use of variable length array
despite being -std=c99. it was irresponsible of me to introduce VLA in
here.

since this function will be called quite often, i did not want to make
calls to malloc and free as they have some overhead.

512 should be sufficient enough and probably is far bigger than any
window title bar can display anyways.
