[fpc-devel] Method for write string into TStream

[thaddy at thaddy.com]

You can always use KOL for that ;)
But anyway: we implemented that at the cost of read-back speed and 
looking for zero termination, which is flawed anyway for object pascal 
strings, since it can contain zero's.
It can be done through RTTI with my usual complaints about that sort of 
shit.

A (abstract) stream can not know if the length is stored or 
not...without rtti.

If you accept polymorhism this is not a good idea. I may be wrong (again)
