Repeated quotes suppressed from log even after being redefined

When the same quote is displayed more than once, it only gets logged the first time although it appears on-screen every time. This seems intentional, so that for example standing on a slime floor with boots doesn't spam the log with the same message over and over.

Unfortunately this also happens when the same quote is reused to display different text (e.g. "TQUOTE" from the examples, using qputs or qsprintf). Since the message has changed, it should probably be logged each time.
