Hello,
after I put in ~/.config/git "[diff] algorithm=histogram", and called "git diff --minimal" I expect from git to use algorithm=minimal. But it uses histogram, unless I call "--diff-algorithm=minimal". According to the documentation, however, --minimal and --diff-algorithm=minimal shall be equivalent.
By the way, histogram produces more compact output than minimal (in terms of number of lines and in terms of @@ ... @@ snippets), but the documentation suggests, that minimal produces the most compact form that can be achieved.
I use git version 2.6.3.385.g1bc8fea.
Greetings Дилян
