Inform about name repair
Muffling and silencing messages
Name repair messages are signaled with inform() and are given the class
"rlib_message_name_repair". These messages can be muffled with
base::suppressMessages().
Name repair messages can also be silenced with the global option
rlib_name_repair_verbosity. This option takes the values:
- "verbose": Always verbose.
- "quiet": Always quiet.
When set to quiet, the message is not displayed and the condition is not
signaled. This is particularly useful for silencing messages during testing
when combined with local_options().
