This is a very simple filter. One common cause of grief (and programmer
error) is that XML parsers arent required to provide character events in one
chunk. They can, but are not forced to, and most dont. This filter does the
trivial but oft-repeated task of putting all characters into a single event.
Note that this wont help you cases such as:
<foo> blah <!-- comment --> phubar </foo>
In the above case, given the interleaving comment, there will be two
character() events. This may be worked around in the future if there is
demand for it.
An interesting way to use this filter, instead of telling users to use it,
is to return it from your handlers constructor, already configured and all.
Thatll make the buffering totally transparent to them (XML::SAX::Writer
