[PATCH v2 2/2] git.c: improve code readability in cmd_main

["Daniel Sonbolian via GitGitGadget" <gitgitgadget@gmail.com>]

From: Daniel Sonbolian <dsal3389@gmail.com>

checking for an error condition whose body unconditionally exists first,
and then the special casing of "version" and "help" as part of the
preparation for the "normal codepath", making the code simpler to read
