bug: backslashes preceding numbers in passwords

[Jesse Norell]

Hello,

  In troubleshooting a client which did not work to unlock the disk at
boot, I found that passwords with a backslash preceding a number are
mishandled.  Eg. here the two char sequence '\1' is converted to the
single char 001:

# KEY='test\1test\two'
# echo -e "${KEY}\n${KEY}" | mandos-keygen --password

(added output to mandos server)

# echo ${KEY} | od -c
0000000   t   e   s   t   \   1   t   e   s   t   \   t   w   o  \n
0000017

# /usr/lib/x86_64-linux-gnu/mandos/plugins.d/mandos-client     --pubkey=/etc/keys/mandos/pubkey.txt     --seckey=/etc/keys/mandos/seckey.txt     --tls-pubkey=/etc/keys/mandos/tls-pubkey.pem     --tls-privkey=/etc/keys/mandos/tls-privkey.pem   | od -c
0000000   t   e   s   t 001   t   e   s   t  \t   w   o
0000014

This is with mandos-client 1.8.14-1 on debian 11 (server is mandos
1.8.14-1~bpo10+1 on debian 10, but I think it's a client issue).

Thanks,
