Subject: [PATCH 04/15] options: make Wsparse_error less special

-Wsparse-error should not be enabled with -Wsparse-all, this is
special cased in the condition in loop handling -Wsparse-all.

However, the condition already handle warnings forced to off.
So instead of explicitly checking for &Wsparse_error, it's enough
to force Wsparse_error off.
