minimizeFilename -- minimize a file name



i1 : minimizeFilename "a/b/c/../d"

o1 = a/b/d
i2 : minimizeFilename "../../../../../../"

o2 = ../../../../../../

Paths of the form foo/x/../bar, are shortened to foo/bar without checking the file system to see whether x is a symbolic link. For the other behavior, see realpath.
