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
