remove the todo entry, which was added when -C was forbidden on the #! line.
However, making -C parsing on the #! more flexible probably requires
removing the "feature" that a C<#line 1> directive triggers re-processing
of #! directives.

-given that all perl command line options are strict ASCII, and -C changes

-calls during startup, and (by implication) a bit of tweaking of that order.
