Harald Nordgren eb5cd8dca6 history: add squash subcommand to fold a range
Folding a series of commits into one required either an interactive
rebase where each commit after the first was hand-edited to "fixup", or
a "git reset --soft" to the merge base followed by "git commit --amend".

Add "git history squash <revision-range>" to do this directly. It folds
every commit in the range into the oldest one, keeping that commit's
message and authorship and taking the tree of the newest commit, then
replays the commits above the range on top. fixup!, squash! and amend!
commits are folded like any other and are not interpreted, so the
squashed message comes from the oldest commit, or from an editor with
--reedit-message.

The range is read like the arguments to "git rev-list", so several
arguments such as "@~3.. ^topic" are allowed. A merge inside the range
is folded when its other parent is reachable from the base, otherwise
the range has more than one base and is rejected. By default the command
also refuses when a ref points at a commit that the fold would discard.
Use --update-refs=head to rewrite only the current branch instead.
