[PATCH v1] scripts/decodecode: Make it take multiline Code line

[Andy Shevchenko]

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.

So, add a 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.
