- logs go into $GL_ADMINDIR/logs by default, named by year-month
- logfile name template (including dir prefix) now in $GL_LOGT
- two new env vars passed down: GL_TS and GL_LOG (timestamp, logfilename)
- log messages timestamps more compact, fields tab-delimited
- old and new SHAs cut to 14 characters
- install is even clearer now (I hope!), esp to people with root
access who seem to expect something else :)
- used path vars (from ~/.gitolite.rc) more consistently, and
- added refeerences to ~/.gitolite.rc for resolving them
