Makes git work with a pure POSIX shell (tested with bash --posix and ash). Right now git causes ash to choke on the redundant shift on line two. Reduces the number of system calls git makes just to do a usage statement from 22610 to 1122, and the runtime for same from 349ms to 29ms on my x86 Linux box. Presents a standard usage statement, and pretty prints the available commands in a form that does not scroll off small terminals. [jc: while shifting when $# was zero was a bug, the original patch failed to shift when it needs to, which I fixed up.] Signed-off-by: Amos Waterland <apw@rossby.metr.ou.edu> Signed-off-by: Junio C Hamano <junkio@cox.net>
