Filter (was Re: Using DropBox for Faster Mobile Development)

I could have accepted the behavior if it was the last line that passed the filter results, and because it did not contain a cr, the result did not end in a cr. But for the filtered results to not have the cr in ANY results regardless of whether or not the last line was included in the results would mean that the filter command is programmed to look to see if there is a trailing cr and then include on in ANY filter results or exclude one in ANY filter results based upon that! What sane reason is there for that??? It may as well check to see if the last char is a tab and so return a tab delimited list!

And I've found from experience that some LC developers think of line formatted lists as a series of lines delimited by return (and I see in their code care being taken to avoid a final return, which would be redundant in that model when there's nothing to delimit); while others think of line formatted lists as a series of lines each terminated by return (and therefore their code takes equal pains to ensure that there's always a return at the end).

It doesn't know from squat whether or not the developer meant to "terminate" or "delimit" and simply forgot to "terminate" the last line. In fact I am not even sure I understand the distinction. In this context "terminate" and "delimit" mean the same thing. There is no termination in LC that I know of.
