[RFC 6/5] Fix ref log parsing so it works properly.

[Shawn Pearce <spearce@spearce.org>]

The log parser was only ever matching the last log record due to
calling strtoul on "> 1136091609" rather than " 1136091609".  Also
once a match for '@' has been found after the name of the ref there
is no point in looking for another '@' within the remaining text.

 Uh yea, I found a couple of bugs.  :-)
 This applies on top of the other 5 patches (hence the 6/5).
