emacs-31 72b8d88171a: Use default-value in project--value-in-dir

branch: emacs-31
commit 72b8d88171a1b1b6a854ee65992228d92352bb73
Author: Zhengyi Fu <[email protected]>
Commit: Dmitry Gutov <[email protected]>

    Use default-value in project--value-in-dir
    
    When in a VC project whose dir-locals file specifies `project-vc-name',
    the function `project--value-in-dir' previously used `symbol-value' to
    retrieve the variable value, causing `project-name' to return the same
    name for all VC projects without an explicit `project-vc-name'.  Use
    `default-value' instead to correctly fall back to the default value.
    
    * lisp/progmodes/project.el (project--value-in-dir): Replace `symbol-value'
    with `default-value' (bug#81293).
