Bug fix -- version grepping in compat.c

[Hamon, Brian K.]

I beg your pardon. The problem was definitely on my end and was unrelated 
to the regular expression I modified. Rebuilding fixed my core dump. I 
still note a minor issue, which may possibly have some impact.

When connecting between two OpenSSH-2.3.0 implementations as follows:

ssh -2 -v host

The debug output contains a "no match" warning:

debug: Connection established.
debug: Remote protocol version 1.99, remote software version OpenSSH_2.3.0p1
debug: no match: OpenSSH_2.3.0p1
Enabling compatibility mode for protocol 2.0

Is the "no match" warning worth addressing? Probably not. I made the change 
in the regular expression and the warning went away. The difference this 
change makes is whether the SSH_OLD_SESSIONID bug fix is applied. This 
appears to be irrelevant.

The "no match" warning could be considered unexpected behavior, but appears 
to have no consequences.
