Suppose I wonder just that. grepping through setup.c for ".git file", I find the function read_gitfile_gently() --- why was that added?

$ git log -Sread_gitfile_gently setup.c

    Add platform-independent .git "symlink"
    
    This patch allows .git to be a regular textfile containing the path of
    the real git directory (prefixed with "gitdir: "), which can be useful on
    platforms lacking support for real symlinks.
