scripts/decodecode: make it take multiline Code line
In case of running scripts/decodecode without any parameters in order to
give a copy'n'pasted Code line from, for example, email it would parse
only first line of it, while in emails it's split to few.
ie, when you have a file out of oops the Code line looks like
Code: hh hh ... <hh> ... hh\n
When copy'n'paste from, for example, email where sender or some middle
MTA split it, the line looks like:
Code: hh hh ... hh\n
hh ... <hh> ... hh\n
hh hh ... hh\n
The Code line followed by another oops line usually contains characters
out of hex digit + space + < + > set.
So add logic to join this split back if and only if the following lines
have hex digits, or spaces, or '<', or '>' characters. It will be quite
unlikely to have a broken input in well formed Oops or dmesg, thus a
simple regex is being used.
