This is really just a pet peeve, since it's not a problem, but...
The "nl" command doesn't number empty lines by default. Is that kind of weird to anyone else?
We can work around this with:
nl -b a <file>
I'm just wondering why:
nl -b t <file>
is the default setting?
Isn't the POSIX definition of a line "something that ends with a newline character"?

So shouldn't "Number Lines" mean "Number *all* lines" *unless* you tell it not to"?
And by "empty line" I mean "A line with 0 characters followed by a terminating newline character".
A line with nothing on it but a newline character is still a line.
@MutoShack It's not what I'd expect naïvely, but thinking about it, skipping blank lines is probably more useful. Bring able to pipe a command's output to another's input was pretty important in old-style Unix. Since many programs treat empty lines specially, the default setting is good if you want downstream programs to act correctly.
