For the first two or three bytes, would an ungetch-like approach work?
The deflate vs gzip compression is really a special case. Guessing is
indeed much more work and involves buffering, for lzma-alone even the
*entire* file content (LZMAv5 is supposed to use a gzip-like header to
fix this problem).

Er, right, 1F 8B 08 it was.

Sometimes they [people] care too much: pretty printers [and syntax highligh-
ting, d.A.] mechanically produce pretty output that accentuates irrelevant
detail in the program, which is as sensible as putting all the prepositions
in English text in bold font.   -- Rob Pike in "Notes on Programming in C"
