The die() error message would presumably include the name of the invalid

If we change the rules for reference names and a bunch of names become
invalid, then it would admittedly be cumbersome to run git N times to
find the N invalid names.  But if we change the rules, then *at that
time* we could always build in iteration over broken reference names.

It's not that I have something against building it iteration over broken
reference names now, as long as it is clearly segregated from "normal"
iteration to prevent illegal names from getting loose in the code.
