I suspect that the latter is "size of a pointer that points at a cmdname structure", but the original code in help_unknown_cmd() is wrong. The ones in load_command_list() do this correctly and another qsort() invocation in this function does so as well. I wonder why they didn't correctly cut&paste ;-) 746c221a (git wrapper: also use aliases to correct mistyped commands, 2008-09-10) seemed to have introduced the culprit. The call to uniq() would fail to uniquify because main_cmds would have the standard command all in front and then aliases and commands in the user's PATH later, but I do not quite see if there is any end-user observable breakages that can arise from this. What is the practical implication of this breakage? No, I am not saying we do not have to fix it; I am just being curious why this patch does not show the existing breakage with a new test.
