RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
dnf --help and dnf man page are inconsistent in some command line options specification, 
e.g. --color, --bzs, --cves, --destdir, --disableexcludepkgs are only 
mentioned in --help output,
on the other hand, --cve, --bz are only in the man page.
All of these options work as expected. 
There could be more such inconsistencies.

Version-Release number of selected component (if applicable):
dnf-4.0.9.2-1.el8

How reproducible:
always

Steps to Reproduce:
1. man dnf
2. dnf --help
3. compare

This is actually a compatibility feature.
DNF/YUM4 works exactly as YUM3:

yum --help | grep '\--bz'
  --bzs=BZS             Include packages needed to fix the given BZ, in

man yum | grep '\--bz'
       --bz=BZS

Would you mind me closing this bug NOTABUG?
Or would you prefer to diverge from the compatibility behavior and make the change?

I'd prefer to have both resources (man and --help) consistent and describing all accepted options. Thanks.
