cli 3.6.0

• The progressr progress handler now reports progress correctly
  (@HenrikBengtsson, #558).

• New hash_*sha1() functions to calculate the SHA-1 hash of strings,
  objects, files.

• cli now shows progress bars after one second by default, if they
  are less than half way at the point. (Or after two seconds,
  unconditionally, as before.) See the the cli.progress_show_after
  option in ?cli-config for details (#542).

• format_inline() now has a new argument keep_whitespace, and it keeps
  whitespace, including newline and form feed characters by default.
