[nongnu] elpa/pdf-tools f42795274c 3/3: Ask for a file name on save if buffer provides none

[ELPA Syncer]

branch: elpa/pdf-tools
commit f42795274c4a34f9e90acec5a9410cee283dc35d
Author: akater <nuclearspace@gmail.com>

    Ask for a file name on save if buffer provides none
    
    When visiting a PDF file downloaded by `eww`, `buffer-file-name` returns
    nil so the file can't be saved. In such a case, we should ask the user
    for a file name instead of failing the operation.
    
    Closes: #178
