This has been suggested in the past.  Unfortunately, truncation to 0
bytes is viewed as a rather destructive operation, so the current
thought is that it is worth making the user do a bit of extra typing to
imply that they meant it.  And you can always write a shell function or
alias to supply the argument automatically, if you like the ease of a
shorter command in an interactive environment.
