Summary: With CVS, only 'head' release displayed

Initial Comment:
CVS release 1.95 for Common.pm tried to sort global variable initialisation by moving $pathname after varaible 'v' being set to the value of $releaseid. Unhappily there is an egg-and-hen problem since $releaseid is set by sub clean_release which references {'variables'}{'v'}{'range'}. It is usually OK but it may be a sub (as in the CVS example in lxr.conf) to compute the range with a call to the SCM class object with argument $pathname to hold the file name.

Since it is undefined at that time, CVS object returns 'head' by default. Afterwards, it is impossible to change version.

GIT uses a different scheme (reading the stored list of releases from a file) and is not affected by this race condition. Plain files usually explicitly enumerates the versions and are also not affected.
