bug with touch t/

[Eric Blake <ebb9 at byu dot net>]

According to POSIX (and as implemented on Linux):

$ rm -Rf t
$ touch t/
touch: setting times of `t/': No such file or directory
$ : > t/
t/: Is a directory.


The ENOENT failure is correct, since you are using the syntax to open (or 
create) a directory but are not going through mkdir.  However, on cygwin, both 
commands mistakenly create the regular file 't'.  This is also an issue with

touch 't\'

which likewise mistakenly creates the regular file 't' by treating \ as an 
alternate directory separator - as a result, the current git checkout of 
autoconf is triggering spurious failures when testing whether the file system 
supports \ embedded in file names rather than as directory separators.
