Merge branch 'as/pretty-truncate'

* as/pretty-truncate:
  pretty.c: format string with truncate respects logOutputEncoding
  t4205, t6006: add tests that fail with i18n.logOutputEncoding set
  t4205 (log-pretty-format): use `tformat` rather than `format`
  t4041, t4205, t6006, t7102: don't hardcode tested encoding value
  t4205 (log-pretty-formats): don't hardcode SHA-1 in expected outputs
