 - `--log_level[=<arg>]`: Control verbosity by passing a number from 0 (most verbose) to 2 (least verbose, only errors).
 - `--ignore_space_changes`: Whitespace changes will be ignored when git is used to produce the diff.
 - `--sniff_unstaged`: Inspect unstaged changes in the working directory against the latest commit (HEAD). `--start_revision` and `--end_revision` will be ignored in this case.
+- `--no_colours`: Do not use coloured output when printing the list of issues.
