Subject: [PATCH] Allow to exclude symlinking of files base on git exclude
 patterns

    HOMESHICK_IGNORE environment variable with comma-separated
    exclude patterns will add entries to .git/info/exclude

    Excluded files will be ignored during symlink step, but still
    can be checked into the repository
