Hi all, TL;DR: why does org-src-mode-configure-edit-buffer set buffer-file-name to a non-nil value? https://code.orgmode.org/bzg/org-mode/commit/4b6988bf36cb458c9d113ee4332e016990c1eb04#diff-ea848b037ba2c0bf95915700bb6f4e539d80d8cR486
Background information: I'm reviewing a patch (https://github.com/flycheck/flycheck/pull/1426) to enable Flycheck in temporary buffers created by org-mode while editing a code snippet with org-edit-src-code (among others). The patch teaches Flycheck to append an checker-appropriate extension to the temporary files that it creates: for example, when editing a Python snippet from an Org file, Flycheck would now create a file named /tmp/<random string>.py instead of /tmp/<random string> (which would make Python happy). We're thinking of enabling this automatic suffix addition behavior only for buffers that do not have a buffer-file-name currently set (in the ones that do, Flycheck already derives file names for its temporary files from the buffer's file name), but we were surprised to find that [* Org src *] actually have a buffer-file-name. Why is that? Thanks, Clément.
