That currently doesn't work on managed mounts, where .exe magic still
happens but trailing dots no longer get stripped. Whatever trick coreutils
uses to undo .exe magic must work in all cases, so it would really be nice
if there were a blessed cygwin syscall that made supressing .exe magic
easy. (Note that undo'ing .exe magic is not done all that often, and that
only a few coreutils must worry about it so that everyone else gets the
benefit).
For that matter, should managed mounts even be doing .exe magic?
$ cd managed
$ ls sh*
ls: sh*: No such file or directory
$ cp /bin/sh.exe sh.exe
$ ./sh # Current behavior:
# New /bin/sh shell is spawned
$ ./sh # Desired behavior:
bash: ./sh: No such file or directory
