Implement data inlined with the index file
This patch allows you to optionally inline data bytes with the
revlog index file. It saves considerable space and checkout
time by reducing the number of inodes, wasted partial blocks and
system calls.
To use the inline data add this to your .hgrc
[revlog]
# inline data only works with revlogng
format=1
# inline is the only valid flag right now.
flags=inline
