fs 1.2.7

New features

• file_size() function added as a helper for file_info("file")$size (#171)

• is_file_empty() function added to test for empty files` (#171)

• dir_tree() function added to print a command line representation of a
  directory tree, analogous to the unix tree program (#82).

• Add a comparision vignette to quickly compare base R, fs and shell
  alterantives (@xvrdm, #168).

Minor improvements and fixes

• path_ext_set() and file_temp() now treat extensions with a leading .
  and those without equally. e.g. path_ext_set("foo", ext = "bar") and
  path_ext_set("foo", ext = ".bar") both result in "foo.bar"

• Tidy paths are now always returned with uppercase drive letters on Windows (#174).

• format.bench_bytes() now works with str() in R 3.5.1+ (#155).

• path_ext(), path_ext_remove(), and path_ext_set() now work on paths
  with no extension, and file_temp() now prepends a . to the file extension
  (#153).

• Link with -pthread by default and fix on BSD systems (#128, #145, #146).

• file_chown() can now take a group_id parameter as character (@cderv, #162).

• Parameter browser in file_show() now works as described in the documentation (@GegznaV, #154).

• path_real() now works even if the file does not exist, but there are
  symlinks further up the path hierarchy (#144).

• colourise_fs_path() now returns paths uncolored if the colors argument /
  LS_COLORS is malformed (#135).
