BOOL
IsValid8Dot3(
    IN LPCTSTR Path
    )

/*++

Routine Description:

    Check whether a path is valid 8.3.  The path may or may not start with
    a backslash.  Only backslashes are recognized as path separators.
    Individual characters are not checked for validity (ie, * would not
    invalidate the path).  The path may or may not terminate with a backslash.
    A component may have a dot without characters in the extension
    (ie, a\b.\c is valid).

    \ and "" are explicitly disallowed even though they fit the rules.

    Stolen from textmode\kernel sptarget.c

Arguments:

    Path - pointer to path to check.

Return Value:

    TRUE if valid 8.3, FALSE otherwise.
