charset: Fix V695: dead branches

Browse Source 
Based on comments it appears that some non-printable characters intended to be 
shown as `|x` (0xA0..0xFE) and some as `~x` (0x80..0x9F, 0xFF, excluding 
previous). But this never happens because this is being catched by condition `c 
>= 0x80` above which makes them be represented as `<A0>`. Since I find this 
variant more useful and it additionally is backwards compatible (Vim does the 
same thing) I just dropped dead branches.
