Use revlogng and inlined data files by default
This changes revlog specify revlogng by default. Inlined
data files are also used unless a flags option is found in the .hgrc.
Some example hgrc files:
[revlog]
# use the original revlog format
format=0
[revlog]
# use revlogng. Because no flags are included, inlined data files
# also be selected
format=1
[revlog]
# use revlogng but do not inline the data files with the index
flags=
[revlog]
# the new default
format=1
flags=inline
#!/bin/sh
hg init
echo foo > a
hg add a
hg commit -m "1" -d "1000000 0"
hg verify
chmod -r .hg/data/a.d
hg verify 2>/dev/null || echo verify failed
chmod +r .hg/data/a.d
hg verify 2>/dev/null || echo verify failed
chmod -w .hg/data/a.d
echo barber > a
hg commit -m "2" -d "1000000 0" 2>/dev/null || echo commit failed
