Actually there is no difference. It doesn't matter one way or other in
situations in gitweb.
I have thought however (but I might be mistaken) that "print {$fh} <sth>"
is idiomatic Perl.
'perldoc -f print' says:
Note that if you're storing FILEHANDLES in an array or other expression,
you will have to use a block returning its value instead:
print { $files[$i] } "stuff\n";
print { $OK ? STDOUT : STDERR } "stuff\n";
Also, there is no "," between FILEHANDLE and LIST in "print FILEHANDLE LIST"
