Fix one compiler warning (STR 3529)

fluid/undo.cxx: fix warning [-Wformat-truncation=]

This fix also removes some static variables and simplifies the
function undo_filename(). It does no longer copy the full filename
string back to a given buffer. Now it returns a pointer to the
internal filename string.

Summary: fix compiler warning, save memory, simplify a function, and
  speed up code by not copying data unnecessarily.
