Default Header value breaks on '='

[ed-george]

When entering a default value for an @apiHeader, the docs do not render correctly when an equals '=' sign is part of the header default. I.e.

E.g. When using Basic Auth for client test@example.com and pass password:
@apiHeader {String} [Authorization=Basic dGVzdEBleGFtcGxlLmNvbTpwYXNzd29yZA==] Basic Auth

This would currently show as
==] Basic Auth Default value: Basic dGVzdEBleGFtcGxlLmNvbTpwYXNzd29yZA

Rather than the expected:
Basic Auth Default value: Basic dGVzdEBleGFtcGxlLmNvbTpwYXNzd29yZA==
