perldiag: Rewrap symref error for better splain output
Before:
(F) You've told Perl to dereference a string, something which use strict
blocks to prevent it happening accidentally. See
"Symbolic references" in perlref. This can be triggered by an @ or $ in a
double-quoted string immediately before interpolating a variable, for example
in "user @$twitter_id", which says to treat the contents of $twitter_id
as an array reference; use a \ to have a literal @ symbol followed by the
contents of $twitter_id: "user \@$twitter_id".
