However this two requirements do not seem reconcilable.

As a further historical note, originally 9P required a stream that preseved
record boundaries, and the reliable datagram protocol IL/IP and pipes did
that. Once TCP/IP was used, there was some fussing needed to work out where
the records were, so the revision 9P2000 added a size and the stream didn
Zero conventionally means end-of-file, but record boundaries are preserved
on capable streams, so if a writer writes zero, the reader reads zero.
Having said that, I think the comment is wrong, and read9pmsg returning
zero should be interpreted as the end of the (9p) stream.
In most cases, the wri

Interesting! Is this "by design"?
And what is the intended usage of 0 writes?
BTW, so fcall(2) is misleading, a 0 read can not be used to identify an
EOF, right?

on plan 9 systems 0 writes are not discarded.

Actually the command is no rocket science. You can simply use hget, sed and
htmlfmt to reach similar things. The 'github' command is a kind of shortcut to
blobs from github repositories.
The --raw mode is the opposite of --blob. I changed the code that *.md files
are automatically read blob fi

Question what does the --raw option do?

Hi Plan9ers,
I wrote a little rc script for my personal use. I want to share it with you, as
it look quite usefull to me (why would I have wrote it otherwise).

Check it out and tell me your thoughts.
