[Regression] Editting stale symlink removes symlink and creates file symlink points to

["Andrew V. Samoilov" <sav bcs zp ua>]

Hello,

Max Derzhak <max /at/linux.zp.ua> reported new regression in mcedit.  If 
you type F4 on stale symlink and press Esc-Esc or F10 after it (no 
editting at all) mcedit creates empty file symlink points to and removes 
original symlink.  This bug is more than annoing, and it was introduced 
after 4.5.55.  Current behaviour should be changed, but 
resolve_symlink() is very expensive, especially over VFS, as far as new 
algorithm for file saving when backup is doing by copying original file 
to new file and then saving new edition to original filename.

Lines below are from edit/Changelog.

        * edit.c (check_file_access): Return 1 on all errors, document
        this behavior.  Set edit->delete_file to 1 for newly created
        files.
        (edit_open_file): Don't set edit->delete_file, it's now done in
        check_file_access().
