The primary idea is to allow `kill-buffer' and `kill-emacs' to
complete even if Emacs has trouble unlocking the buffer's file.
* lisp/userlock.el (userlock--handle-unlock-error): New function, call
`display-error'.
* src/filelock.c (unlock_file_body): New function, do what
'unlock_file' used to.
(unlock_file_handle_error): New function, call
`userlock--handle-unlock-error' with the captured error.
(unlock_file): Handle `file-error' conditions by calling the handler
defined above.
* test/src/filelock-tests.el (filelock-tests-kill-buffer-spoiled):
(filelock-tests-unlock-spoiled): Modify to test new behavior.
This directory contains the architecture-independent files used by or
with Emacs. This includes some text files of documentation for GNU
Emacs or of interest to Emacs users, and the file of dumped docstrings
for Emacs functions and variables.
