[bug#32287] [PATCH] Reproducible svn checkouts

[Ludovic Courtès]

Hi Julien,

Ouch, good catch.

Did you find packages that would trigger this issue?  We should somehow
check all the packages that use ‘svn-fetch’ when we merge this patch,
and update hashes as needed.

‘find-files’ doesn’t include directories by default; we also need a
stricter regexp, leading to:

  (for-each delete-file-recursively
            (find-files "." "^\\.svn$" #:directories? #t))

WDYT?

(I’ll be AFK so feel free to apply if it looks good to you.)
