or https URL to be important. Defaults to false. See
linkgit:gitcredentials[7] for more information.
credential.sanitizePrompt::
By default, user names and hosts that are shown as part of the
password prompt are not allowed to contain control characters (they
will be URL-encoded by default). Configure this setting to `false` to
override that behavior.
credential.protectProtocol::
By default, Carriage Return characters are not allowed in the protocol
that is used when Git talks to a credential helper. This setting allows
users to override this default.
credential.username::
If no username is set for a network authentication, use this username
by default. See credential.<context>.* below, and

are masked, except ANSI color sequences. This prevents potentially
unwanted ANSI escape sequences from being sent to the terminal. Use
this config setting to override this behavior:

--
color::
Allow ANSI color sequences, line feeds and horizontal tabs,
but mask all other control characters. This is the default.
false::
Mask all control characters other than line feeds and
horizontal tabs.

Allow all control characters to be sent to the terminal.
