Log Message:
(sysutils/R-processx) Updated 3.4.5 to 3.5.2

# processx 3.5.2

* `run()` now does not truncate stdout and stderr when the output
  contains multibyte characters (#298, @infotroph).

* processx now compiles with custom compilers that enable OpenMP (#297).

* processx now avoids a race condition when the working directory is
  changed right after starting a process, potentially before the
  sub-process is initialized (#300).

* processx now works with non-ASCII path names on non-UTF-8 Unix platforms
  (#293).

# processx 3.5.1

* Fix a potential failure when polling curl file descriptors on Windows.

# processx 3.5.0

* You can now append environment variables to the ones set in the current
  process if you include `"current"` in the value of `env`, in `run()`
  and for `process$new()`: `env = c("current", NEW = \ 
"newvalue")` (#232).

* Sub-processes can now inherit the standard input, output and error from
  the main R process, by setting the corresponding argument to an empty
  string. E.g. `run("ls", stdout = "")` (#72).

* `run()` is now much faster with large standard output or standard
  error (#286).

* `run()` can now discard the standard output and error or redirect
  them to file(s), instead of collecting them.

* processx now optionally uses the cli package to color error messages
  and stack traces, instead of crayon.
