- usage() gets a little smarter; it now knows what function it was called
from and tries to find a '=for function_name' chunk of data in the script
- the various list-* functions now work off a dispatcher in Load.pm
- (...and they all use the new usage() magic to print their helps!)
- src/gitolite got a lot leaner due to this dispatcher
- src/gitolite-shell became a lot more easier to read/flow
- rc acquired '{COMMANDS}', which gitolite-shell now refers to
- comments in the default rc file changed a bit
- rc got a new REMOTE_COMMAND_PATT (in place of ADC_CMD_ARGS_PATT)
the rest is perltidy and stuff like that
