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'
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.

The use of "declare -A flaghash" (associative array) was introduced
in PR #205, which works perfectly for Bash 4.x, but OS X insists on
shipping a very outdated Bash 3.2.x.
This patch hides the "bash: declare: -A: invalid option" error message
and allows the bash completion script to continue gracefully on
OS X, albeit without the benefit of the new feature in PR #205.
Fixes#240
Just like the last commit, but now for manpages.
genMan still works with a buffer and returns []byte instead of working
directly with an io.Writer. This is because, in turn, md2man takes byte
slices instead of readers and writers.
Wrapping genMan around a writer is unnecessary especially since it's not
an exported function, and also because we'd still need a buffer to get
the output bytes.
