Subject: another useless use of scalar
X-Git-Url: https://sipb.mit.edu/gitweb.cgi/ikiwiki.git/commitdiff_plain/c5642119f7fafdafdaff05c0d37e787de221e9e2?ds=sidebyside

another useless use of scalar

scalar(undef) is undef, so using scalar here had no effect.
Instead make the function return "", probably avoiding an uninitialized
value warning.
