Because it allocates memory for argument interpolation and charser
conversion.

Because in most places, a pool is already available. I suppose we could
make the pool parameter optional and have svn_cmdline_printf create its
own pool if it's NULL, but that would make this function inconsistent
with every other function in Subversion that creates a pool.

I don't think there are that many places where a pool is not already handy.

Oh fi. We have guidelines for that. See HACKING, section "APR pool usage
conventions".
