debugdeltachain: avoid division by zero when a chain is empty...

debugdeltachain: avoid division by zero when a chain is empty The two ratios chainratio and extraratio are computed using dividers that may be zero when the file is empty. As the denominators are integers, the limit of the ratio "just before zero" is the numerator value itself. If the numerator itself is zero, the ratio value is still meaningful: in both cases, a "good" value is a low ratio, and a size of zero is the optimal case.

Mercurial

Mercurial is a fast, easy to use, distributed revision control tool for software developers.

Basic install:

$ make            # see install targets
$ make install    # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg              # see help

Running without installing:

$ make local      # build for inplace usage
$ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation instructions, platform-specific notes, and Mercurial user information.
