hex expression shared the esc_hex expression before.
But esc_hex is limited to 2 hexdecimal characters, and thus poor choice
for parsing hexdecimal numbers in source. (This is different from C
which allows "n" length hex escapes causing problems when you mix hex
escapes with strings for example)

The word label is mainly meant to define printable and conceated
characters. In print_mark we use it to print tail in case we hit the
valid* kleene star expression. Otherwise we will just show '^' mark on
whatever byte we failed on. This allows to catch semantical failures
such as having newlines at wrong place etc..

Combine tail action into mark.
Tokenize on 'space <valid>' or on punctuation.
Treat single printable or valid* as word.

Just some hardening: p should always be equal or behind pe.

If we stop before reading the "p" false positive may be returned since
"p" may be the start of new token.
Thus case like `type: 3u8[4] str;` would fail to mark the real error
since '3' is not read. Thus start marking from the last valid token
that is ':'.

This is to have nice aligned output when outputting byte arrays for
example.
