IMO, when a path contains two consecutive path delimiters then something is wrong.
It could also be that someone wanted to type a letter between both delimiters so dropping
one of them is trying to guess what the user wanted which leads to errors in most cases.
Suddenly a file or directory is accessed that was not meant by the user.
A path should be correct and no more or less smart second guessing should be done.
Otherwise you can also start a "nearest match" search that tries to find another directory
in case the specified one is not found. That's something I would expect in C but not in Pascal.
And even if the WinAPI allows such flaws I don't think that Pascal programmers like this too.
