I would like to set an sbuf with a 'potential' buffersize.
So long as I have not reached the 'potential' maximum, an
operation will not overlflow, though it may not have origianlly
allocated so much memeory, or at least it may not always have that much...
e.g. I would like to guarantee that a bunch of operations succeed,
and then when I close the string maybe, it uses an appropriatly
sized buffer. An operation to truncate back to some know size,
after I have successfully completed the operations
and an sbuf_getpos() would also be in my wishlist, as well as the ability
to work WITHIN a longer already filled out string..
(e.g. insert, delete, replace :-)
