sub ParseData is fully backwards compatible. If some module runs it in list
context, then it will get listified hash like previously. New code should
always run it in scalar context though (everything in our code base
was changed according to that).
sub GetTextRevision is not backwards compatible (don't let “wantarray” usage
to confuse you). Most modules do not touch that subroutine, so we are probably
fine (modules from our git repo that do use were changed accordingly).
“EncodePage(%$page)” looks wrong. It seems like we should change it to accept
hash ref.
Recently, uploaded files don't just contain #FILE and a MIME type --
the MIME type is followed by a space and optionally more information.
I replaced the hand-coded parsing with a call to TextIsFile and added
better error checking and fixed the error messages (they used $s
instead of %s).
