flag: ignores failures when the flag is not parseable into a boolean

[gopherbot]

What steps will reproduce the problem?
If possible, include a link to a program on play.golang.org.
1. Create a new flagset and set the error handling to anything.
2. Register a boolean flag.
3. Parse the command arguments and print the value of any errors returned.
3. Run the program and pass a non boolean variable to the flag (something other than
'true' or 'false')
4. Example:  http://play.golang.org/p/tb_09vpnl9

What is the expected output?
Perform whatever the error handler dictates, either panic, exit, or continue on error
(returning the error).

What do you see instead?
The flag usage is printed, but we return from the Parse(..) function normally with a nil
error.
