Thanks, pushed to the emacs-26 branch (will be merged to master from

 Opening PDF attachments in Gnus with doc-view-mode causes error on
 Windows

Hi,

I'm running Emacs 26.1 on Windows 10. I've replicated this with "emacs -Q"

In a gnus article buffer, opening a PDF attachment in doc-view causes
doc-view to fail with the error:
  File error: "Opening output file", "Invalid argument", "c:/Users/Jordan/Emacs/.cache/docview-cache/ *mm*-012345" 

this leaves a buffer showing the file literally. If I rename that buffer
to something not containing an asterisk, it displays fine when running
"doc-view-mode". Windows apparently can't handle asterisks in
directory/file names.

Thanks
