README link semi-fix

the apparent need for "cvs2git-wrap/" in [[link]]
 seems to be a shortcoming of having a README.mediawiki

As viewed from https://github.com/Anacode/cvs2git-wrap
 we need [[cvs2git-wrap/Ana_VC_general.mediawiki]]
but from https://github.com/Anacode/cvs2git-wrap/blob/master/README.mediawiki
 plain [[Ana_VC_general.mediawiki]]
