PATCH: Datafellows SSH misdetection in compat.c

[Pekka Savola]

Hello all,

All SSH/Datafellows versions don't match properly in compat.c.  This
should be fixed in OpenBSD version, naturally.  An example of this is:

debug: match: 2.1.0.pl2 SSH Secure Shell (non-commercial) pat ^2\.

The match should definitely be 2.1.0.  This is caused by the fact that
a requisite space was added to the check when converting to regexp matching
on Oct 10; CVS Id 1.24:

http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/compat.c?r1=1.23&r2=1.24

Patch attached.
