crypt.3: Clarify that ending of the salt string with '$' is optional
In crypt/sha512-crypt.c::__sha512_crypt_r() and the similar
sha256 function, the length of the actually used salt is
calculated as:
salt_len = MIN (strcspn (salt, "$"), SALT_LEN_MAX);
Thus the trailing '$' is optional in the salt string. One can
check that
crypt("key", "$5$salt")
yields the same result as
crypt("key", "$5$salt$").
