[Pharo-project] Fuel version 1.4 uses #isBinary, and SIXX uses #tab:

[Yanni Chiu]

FLBufferedWriteStream>>sizeBuffer: calls #isBinary, which is not 
currently implemented by FSWriteStream - probably because #isBinary is 
not specified by ANSI. Is there a reason why the stream is not always 
binary?

Also, when using SIXX with FSWriteStream, I had to add the non-ANSI 
#tab: method to FSWriteStream. There's probably a dozen calls to #tab: 
in the SIXX code. Should #tab: be added to FSWriteStream somehow? Maybe 
a non-ANSI streams extension package?
