SvPOK(sv) must be true and the C<ptr> must be a pointer to somewhere inside
the string buffer. The C<ptr> becomes the first character of the adjusted
string. Uses the "OOK hack".
+Beware: after this function returns, C<ptr> and SvPVX(sv) may no longer
+refer to the same chunk of data.
void sv_chop(SV* sv, char* ptr)
(SvFAKE and name of '&' is not a meaningful combination currently but could
become so if C<my sub foo {}> is implemented.)
+Note that formats are treated as anon subs, and are cloned each time
+write is called (if necessary).
