Well it is certainly safer to cd on a directory. But 8.3. names
doesn't work with files either: While miktex I can compile

pdflatex test-t~1

without problems, with texlive 2014 I get "! I can't find file
`test-t'".

miktex is also able to compile a document in a longer path with ~.

In both systems it works to use environment variables:

pdflatex %USERPROFILE%\documents\testtesttest\test
