Why does a reverse hexdump truncate the message?
$ echo "4c 6f 72 65 6d 20 69 70 73 75 6d 20 64 6f 6c 6f 72 20 73 69 74 20 61 6d 65 74 2c 20 63 6f 6e 73 65 63 74 65 74 75 72 20 61 64 69 70 69 73 63 69 6e 67 20 65 6c 69 74 2c" | xxd -r

The actual message here is much longer, but the first letter and most of the rest are not shown. Why not?

From man xxd, the section on the -r flag (emphasis added):
-r | -revert
reverse operation: convert (or patch) hexdump into binary. If not writing to stdout, xxd writes into its output file without truncating it. Use the combination -r -p to read plain hexadecimal dumps without line number information and without a particular column layout. Additional Whitespace and line-breaks are allowed anywhere.
