Fossil

much work gets applied — just one check-in or a whole branch — and the
merge direction.  This is the sort of thing we mean when we point out
that Fossil's command interface is simpler than Git's: there are fewer
concepts to keep track of in your mental model of Fossil's internal
operation.

Fossil's implementation of the feature is also simpler to describe. The
online help for <tt> [/help?cmd=merge | fossil merge]</tt> is currently
41 lines long, whereas the aggregate man page length for the above three
Git commands is over 1000 lines, much of it mutually redundant. (e.g.
the <tt>--edit</tt> and <tt>--no-commit</tt> options get described three
different times, each time differently.)
brief online help for <tt>[/help?cmd=merge | fossil merge]</tt> is
currently 41 lines long, to which you want to add the 600 lines of
[./branching.wiki | the branching document]. The equivalent
documentation in Git is the aggregation of the man pages for the above
three commands, which is over 1000 lines, much of it mutually redundant.
(e.g.  the <tt>--edit</tt> and <tt>--no-commit</tt> options get
described three different times, each time differently.) Fossil's
documentation is not only more concise, it gives a nice split of brief
online help and full online documentation.

Fossil started out using 160-bit SHA-1 hashes to identify check-ins,
just as in Git. That changed in early 2017 when news of the
