Improve a couple of log messages. (pantsbuild#13121)

- Our log messages are usually capitalized, so the preserving local process dir one should be too.
- backtick-double-quote-path is much harder to select and copy than just the raw path string.
- The dot at the end of the getting-help URL might be selected and copied, which would be wrong.
