2017-05-13	Factor LZ77 and Huffman routines out of deflate.c.	Simon Tatham
	The general routines for analysing a buffer into an LZ77ish stream of literals and matches, and for constructing a Huffman tree in canonical format, now live in their own source files so that they can be reused for other similar compression formats. Deflate-specific details like the exact file encoding are left in deflate.c.
2014-10-01	Apply the same Deflate decoder fix as PuTTY r10278.	Simon Tatham
	This causes sensible error reporting if distance codes 30 or 31 appear in a compressed block. (Not that Halibut actually _uses_ the Deflate decoder - it only uses the encoder - but if I've got a copy of this code here then it should be correct.) [originally from svn r10280] [r10278 == 3fd8014ea7235d0ec34e8f97a34f3ecf576e8239 in putty repository]
2014-03-30	Silence compiler warnings on OS X 10.9.	Simon Tatham
	[originally from svn r10166]
2012-06-03	Patch from Maciej Adamczyk to set standard output to binary mode in	Simon Tatham
	the standalone deflate utility modes, so you can redirect output to a file and end up with correct data in that file. [originally from svn r9552]
2012-06-01	Make the Deflate decoder correctly handle the special case of a	Simon Tatham
	dynamic block in which the backward-distances Huffman table contains no entries at all. (In this situation it's impossible to use the distance table, and therefore the block must contain nothing but Huffman-coded literals.) [originally from svn r9550]
2012-05-03	Apply r6972 from my other copy of deflate.c: don't lose the BFINAL bit	Simon Tatham
	on an uncompressed block. [originally from svn r9482] [r6972 == 37af901cfe63ed062306e3835751e9b8e089e252 in misc repository]
2012-05-03	Ahem. Don't invert the length _twice_.	Simon Tatham
	[originally from svn r9476]
2012-05-03	Add an error check for correct formatting in Deflate uncompressed	Simon Tatham
	block headers. (Ubuntu 12.04's gcc spotted that nlen was unused, which it shouldn't have been.) [originally from svn r9475]
2008-11-21	Clean up some compiler warnings.	Simon Tatham
	[originally from svn r8310]
2007-02-13	When building the static Huffman tables, it's vital to include the	Simon Tatham
	two unused entries at the end of the lit/len table (286 and 287), because without them all the 9-bit codes are off by four. I can only assume I hadn't noticed this before because no test file I've compressed had both (a) contained byte values >= 0x90 and (b) required a static block. [originally from svn r7279]
2006-12-07	Fix typo in limit test in deflate_buildhuf(). (The only two limit	Simon Tatham
	values ever used are 15 and 7, so testing against 16 is silly.) [originally from svn r6969] [this svn revision also touched misc]
2006-12-06	Update deflate.c to include nearly all the changes I've been making	Simon Tatham
	in the main version. The one missing thing is the fancy new LZ77 compressor in misc/libcode/lz77.c, in whose stability I'm not yet confident enough to consider it ready for prime-time. [originally from svn r6967]
2006-11-30	Add support for compressed PDF streams, using Simon's new deflate library.	Ben Harris
	[originally from svn r6931]
