Merge persistent flags before checking for a help flag

67feb8173c Add support for setting a function to handle flag parsing errors. 
The default pflag error is to only print the bad flag. This enables an application
to include a usage message or other details about the error.

7bf964e5b6 Do not show subcommands in bash completion if a local flag was specified 
If a user specifies a flag to a command which doesn't make sense to a
subcommand do not show subcommands as a suggestion.

This also changes things to show both 'required flags' and 'commands'
instead of only 'required flags'

e14e47b7a9 Issue #267: Ensure hidden flags/subcommands do not change help 
If a command has one flag which is hidden, it should not, for
instance, show the `Flags: ` heading.  Likewise there are other
items in the help template which should respect hidden/deprecated
state.

e5762054c9 Limit the verbose test workaround to "cobra.test" only 
so that full path to the executable or a renamed executable
parses command-line arguments correctly as before.

Special thanks to @apriendeau for discovering "go test -v" failing
and for providing the initial workaround, see #155 and subsequent
discussions.

8af2b2b89f No newline after Flags in usage 
The flags usage template from pflags has a trailing \n. We need to
include a newline in case there are no flags in our template. This will
trim the newline from the end of the flags from pflag and we can do it
right outselves.

3eac1434ef Update IsAvailableCommand checks 
This slightly changes IsAvailableCommand in that a non-runnable command
with a runnable subcommand is now 'Available'

We also use IsAvailableCommand in the rest of the codebase instead of
half kinda sorta doing it incorrectly other places.
