Just to clarify, when I mentioned strstr(), I meant it as an example of
using some existing implementation (instead of creating something new)
rather than suggesting strstr() is the "best" one. If there's something in
Scintilla which would make it easier to implement this feature, just go for
it. If there's some performance problem, it can always be improved
afterwards (but I don't think there will be any).
