Merge branch 'ei/oneline+add-empty'

* ei/oneline+add-empty:
  Fix ALLOC_GROW calls with obsolete semantics
  Fix ALLOC_GROW off-by-one
  builtin-add: simplify (and increase accuracy of) exclude handling
  dir_struct: add collect_ignored option
  Extend --pretty=oneline to cover the first paragraph,
  Lift 16kB limit of log message output
