> So, bug or no bug? And is it just funny on F7 or can you repro it elsewhere The current documentation says: | On older systems, the leading `-' can be replaced by `+' in the | obsolete option syntax with the same meaning as in counts, and obsolete | usage overrides normal usage when the two conflict. This obsolete | behavior can be enabled or disabled with the `_POSIX2_VERSION' | environment variable (*note Standards conformance::), but portable | scripts should avoid commands whose behavior depends on this variable. so basically it was disabled as it violated the required standards compliant behaviour
