Under that argument, "printf %d -" shouldn't report an error either, 
because "-" doesn't contain anything other than what could appear in an 
integer.

Anyway, this isn't an issue of personal preference, as POSIX says printf 
must diagnose anything that isn't a valid C integer constant, and the 
empty string is clearly not such a constant. If Bash is in POSIX mode it 
must issue a diagnostic, and there's little reason for Bash's non-POSIX 
mode to differ.
