[tex-live] tilde in file/folder names (again)

[Ulrike Fischer]

Due to a question on the miktex bug tracker I made some tests with
folders and file names with a tilde in it on windows10.

There was a long discussion about this in 2014, and there Akira
claimed that on texlive 2015 it should work:

But all my tests in tl15 and tl16 (and miktex) fail. 
They fail due to the active tilde with plain and latex, even if the
file names are quoted:

G:\>pdftex "Z-Temp\~foo\test-tilde"
This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live
2016/W32TeX) (preloaded format=pdftex)
 restricted \write18 enabled.
entering extended mode
! I can't find file `./Z-Temp/'.
<to be read again>
                   \penalty
~->\penalty
            \@M \
<*> ./Z-Temp/~
              foo/test-tilde.tex


G:\Z-Temp\~foo>pdftex "~test-tilde"
This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live
2016/W32TeX) (preloaded format=pdftex)
 restricted \write18 enabled.
entering extended mode
(d:/texlive/2016/texmf-dist/tex/latex/tools/.tex File ignored)

G:\Z-Temp\~foo>pdftex "test~tilde"
This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live
2016/W32TeX) (preloaded format=pdftex)
 restricted \write18 enabled.
entering extended mode
! I can't find file `./test'.
<to be read again>
                   \penalty


with the other engines (xetex, luatex) one gets similar results.

Has there be some regression?
