Merge branch 'zk/difftool-counts'
Show the total number of paths and the number of paths shown so far when "git difftool" prompts to launch an external diff tool, which would give users some sense of progress. * zk/difftool-counts: diff.c: fix some recent whitespace style violations difftool: display the number of files in the diff queue in the prompt
Diffstat (limited to 'diff.c')
