There is a small issue here that I can't solve. Imagine there is
"Content-Length" header bt with empty value, and the next header has a
numeric header name:

-------
Content-Length:
1234: blablabla
-------

In that case the code above returns 1234 while it should return 0.

Demostration:

"Via: via1,via2,\r\n via3\r\nFrom: from_user@domain\nContent-length:
\r\n1234: blabla\nTo: to_user@domain\n"[/content-length\s*:\s*(\d+)/i,
1].to_i
=> 1234


I'm trying to solve it by ading [^(\r|\n)] after (\d+) but I get
nothing. Please, could you help me with this?

Thanks a lot in advance and best regards.
