`rev-parse --verify` swallows --end-of-options, but --symbolic-full-name
deliberately echoes it -- on every git version tested, 2.25 through 2.49:
$ git rev-parse --symbolic-full-name --end-of-options feature
--end-of-options
refs/heads/feature
resolveSymbolicFullName took the first non-empty line, so it returned the literal
string "--end-of-options" instead of the ref. That value flows into
gitHistoryRefFromFullName, matches none of the refs/heads, refs/remotes, or
refs/tags prefixes, and every named branch and tag in git history was silently
categorized as a plain commit with a garbage id.
Skip the marker line. Version-independent bug; no test covered it.
Also pins git's echo behavior in the real-binary compatibility suite, so if a
future git stops emitting the marker the reason for the skip gets re-read rather
than the assumption quietly rotting.
