[PATCH] allow literal percent sign in logformat strings

[Andr� Malo]

This is a feature, I'm already missing a long time. However, the attached 
patch allows the percent sign to be put into the log format string "as 
usual", for example:

LogFormat '... %{deflate-ratio}n%% ...'

would result in "... 56% ..."
