Show the corresponding bootstrap error

After setting the drush dependencies in the command hook to specify the requirement of another drush command, I noticed that the command indeed didn't execute, but I saw strange error output:

Command xxxxx needs the following module(s) enabled to run: xxxxx.                                            [error]
The drush command 'xxxxx' could not be executed.                                                              [error]

After looking at the bootstrap process and drush_enforce_requirement_drush_dependencies(), I noticed that
$command['bootstrap_errors']['DRUSH_COMMAND_DEPENDENCY_ERROR'] was being set with the error message, but because
if ($bootstrap_result && empty($command['bootstrap_errors'])) {
shows that the bootstrap_errors aren't empty, $command_found is not being set to TRUE. Thus... invoking the disabled module error above.
