Fish calls an internal shellscript function called __fish_describe_command in order to find a description for a command. Actually, it finds descriptions for all commands beginning with a specified prefix, so if you call '__fish_describe_command git' you will get a list of descriptions for all git subcommands. What __fish_describe_command actually does is that it uses the apropos command to search the whatis database (which in turn is generated by from the manual pages installed in the system). Unfortunatly, the definition of the __fish_describe_command is a bit of an abomination, because the actual format of the apropos output varies significantly between platforms and even between Linux distributions. Hope that answers you question, and that you'll be sending us a patch containing lots of git tab completions soon!
