Well said. I share your opinion. To your question
...you say "not handling 0 filenames is a bug". Based on what criteria do you draw that line?I want to give a nucleus for a hopefully intersting discussion. Can it be that user's or programmer's expectation is the driving criteria?
To stick at the filename example (which shouldn't be in the focus of my thread), years ago nobody expected that filenames containing non-ascii characters would work, but nowadays I'm pretty sure that users expect to be able to write e.g. German umlauts in their filenames.
Are common expectations (yes, yes, it's very vague) a kind of implicit, unwritten requirement? :-)
