Many instances of duplicate words (e.g. "the the path") and
a few typoes are fixed, originally in multiple patches.

    wildmatch: fix duplicate words of "the"
    t: fix duplicate words of "output"
    transport-helper: fix duplicate words of "read"
    Git.pm: fix duplicate words of "return"
    path: fix duplicate words of "look"
    pack-protocol.txt: fix duplicate words of "the"
    precompose-utf8: fix typo of "sequences"
    split-index: fix typo
    worktree.c: fix typo
    remote-ext: fix typo
