As v1.6.0-rc2~42 (Allow "non-option" revision options in parse_option-enabled commands, 2008-07-31) explains, options handled by setup_revisions fall into two categories:
1. global options like --topo-order handled by parse_revision_opt,
which can take detached arguments and can be parsed in advance; 2. pseudo-options that must be parsed in order with their revision
counterparts, like --not and --all.The global options are taken care of by handle_revision_opt; the pseudo-options are currently in a deeply indented portion of setup_revisions. Give them their own function for easier reading.
The only goal is to make setup_revisions easier to read straight through. No functional change intended.
