As last resort, default value of 80 chars will be used.
+Calling C<term_width> with a true value will cause it to be recalculated; you
+can use this to cause it to get recalculated when your terminal is resized like
+this
+
+ $SIG{WINCH} = sub { Catalyst::Utils::term_width(1) };
+
=cut
my $_term_width;
sub term_width {
+ my $force_reset = shift;
+
+ undef $_term_width if $force_reset;
+
return $_term_width if $_term_width;
my $width;
