* fixed potential buffer overflow error when creating the fullprocname for

display purposes if there was a parameter with a default value > 255 chars
  * replace #0, #10 and #13 in the fullprocname with '.' so they do not cause
    line breaks or early string termination when writing them to the
    assembler file (mantis #17928)
