git bash completion now handles git alias options. It means that options
which change the completion behavior for complete commands will also
change the behavior of completion for aliased command.
bash completion now handle git alias options. I did a use case in another
commit: a checkout alias which only complete local branches, ie. only
'refs' ones, not 'remotes'. With this new alias completion, I added an
option to do that in checkout command and hacked _git_checkout complete
function.
This is a draft version, bash usage should be improved. To achieve this:
* a global array $alias_words is filled. As it is global and this file
sourced, this variable can be seen from the terminal
* __git_aliased_command fills $alias_words
* __git_aliased_command must be called differently (not in a subshell)
to fill the global variable. The return value $expansion is
passed by reference as a parameter
* __git_find_on_cmdline now search in $words and $alias_words
