The spec clearly defines that tokens are separated with SPACE TAB or
NEWLINE, which seems unambiguous to me. Multi-line entries are an
inherent part of the file format, and are useful for readable layout.
For an example, see:
    http://www.catb.org/esr/writings/taoup/html/ch10s03.html

It's perfectly ok to parse an extended version of the file format which
allows for quoting and escaping mechanisms, but not if it is done is a way
which is incompatible with reasonable and well formed existing files.

Disallowing NEWLINE as a token separator means you are not parsing an
extension of the existing format, but something incompatible with it.
That's fine as it offers useful features, but it should use a different
file name to make it clear that it is not the same format.
