xemacs 21.5.26 and case-insensitive file systems

XEmacs on MacOS treats the file system case-sensitively, and deals badly with files that have spaces in their names (which are common here). The major culprits in these bugs are: 1) minibuffer completion of file name case; 2) *shell* buffer completion of file name case; 3) *shell* buffer completion of file names with backslash-quoted spaces; 4) *shell* buffer tracking of the current directory when the directory has a space; 5) shell-resync-dirs when the current directory has a space. I've fixed 1, 2, and 3, below. 4 and 5 still elude me. Someone really ought to grep the whole tree for "completion-ignore- case" and "windows-nt", because there are incorrect assumptions hardcoded in several places.
