DeprecatedLower() looks deprecated, perhaps you can
use LowerASCII() instead?
Also, make |capture| const.

Done.

[mcasas, 2017/04/26 19:27:36]

This is implied by l.1686. What about:

if (capture == "user")
  return capture;
// |capture| is equivalent to 'environment' if unspecified.
return "environment";

[riju_, 2017/04/27 12:30:19]

Done.
