Problem: [security] xxd: buffer-overflow with specific flags
Solution: Correctly calculate the required buffer space
(Lennard Hofmann)
xxd writes each output line into a global buffer before printing.
The maximum size of that buffer was not calculated correctly.
This command was crashing in AddressSanitizer:
$ xxd -Ralways -g1 -c256 -d -o 9223372036854775808 /etc/passwd
This prints a line of 6680 bytes but the buffer only had room for 6549 bytes.
If the output from "-b" was colored, the line could be even longer.

Commit f6fc255e8d (v9.0.1834) updated xxd.1 but the xxd.man
page wasn't re-generated. So let's just regenerate it now.
