Merge branch 'jc/fetch'
* jc/fetch: .gitignore: add git-fetch--tool builtin-fetch--tool: fix reflog notes. git-fetch: retire update-local-ref which is not used anymore. builtin-fetch--tool: make sure not to overstep ls-remote-result buffer. fetch--tool: fix uninitialized buffer when reading from stdin builtin-fetch--tool: adjust to updated sha1_object_info(). git-fetch--tool takes flags before the subcommand. Use stdin reflist passing in git-fetch.sh Use stdin reflist passing in parse-remote Allow fetch--tool to read from stdin git-fetch: rewrite expand_ref_wildcard in C git-fetch: rewrite another shell loop in C git-fetch: move more code into C. git-fetch--tool: start rewriting parts of git-fetch in C. git-fetch: split fetch_main into fetch_dumb and fetch_native
