The default function name discovery already works quite well for Perl
code... with the exception of here-documents (or rather their ending).
sub foo {
print <<END
here-document
END
return 1;
}
The default funcname pattern treats the unindented END line as a
function declaration and puts it in the @@ line of diff and "grep
--show-function" output.
With a little knowledge of perl syntax, we can do better. You can
try it out by adding "*.perl diff=perl" to the gitattributes file.
