SZEDER Gábor 424cce832d bash: support user-supplied completion scripts for user's git commands ... The bash completion script already provides support to complete aliases, options and refs for aliases (if the alias can be traced back to a supported git command by __git_aliased_command()), and the user's custom git commands, but it does not support the options of the user's custom git commands (of course; how could it know about the options of a custom git command?). Users of such custom git commands could extend git's bash completion script by writing functions to support their commands, but they might have issues with it: they might not have the rights to modify a system-wide git completion script, and they will need to track and merge upstream changes in the future. This patch addresses this by providing means for users to supply custom completion scriplets for their custom git commands without modifying the main git bash completion script. Instead of having a huge hard-coded list of command-completion function pairs (in _git()), the completion script will figure out which completion function to call based on the command's name. That is, when completing the options of 'git foo', the main completion script will check whether the function '_git_foo' is declared, and if declared, it will invoke that function to perform the completion. If such a function is not declared, it will fall back to complete file names. So, users will only need to provide this '_git_foo' completion function in a separate file, source that file, and it will be used the next time they press TAB after 'git foo '. There are two git commands (stage and whatchanged), for which the completion functions of other commands were used, therefore they got their own completion function.
