Update french translation

all is in the title :-)

BTW I would like to request such feature in gpgkeymgr : 
 - recursively get all keys which signed a certificate from keyserver (with a configurable deep, 2 may implies already to get a huuge number of OpenPGP keys if starting from a addicted-to-keysigning-party ...) 

I just have discover how to do it in cmd line :
#deep=1
KEYID=1E42B367 # to select the starting certificate
gpg --check-sigs --with-colon $KEYID   | awk -F: '$1 == "sig" && $2 == "?"  { print $5 }'   | sort | uniq | xargs gpg --recv-keys
#deep=2
KEYID="$(gpg --check-sigs --with-colon $KEYID   | awk -F: '$1 == "sig"  { print $5 }'   | sort | uniq)"
gpg --check-sigs --with-colon $KEYID   | awk -F: '$1 == "sig" && $2 == "?"  { print $5 }'   | sort | uniq | xargs gpg --recv-keys # (idem)
#....
