+Subject: Fix compiling templates under Perl 5.26 without '.' in @INC
+
+Perl 5.26 changes the default contents of @INC to no longer include
+".", which is required for "require q[foo.tpl]" semantics.
+
+This breakage is invisible in tests  due to a workaround P5P put in
+place to avoid breaking tests, by setting PERL_USE_UNSAFE_INC=1 in
+Test::Harness and CPAN installers, which makes '.' re-appear in @INC
+during installation, while still being silently broken in production.
+
+This fix works by relying on the mechanic of require() to *NOT* consult
+@INC if $path is either an absolute, or a "./" prefixed relative path,
+by converting it to an absolute path just before requiring it.
