[PATCH] completion: improve doc for complex aliases

["Philippe Blain via GitGitGadget" <gitgitgadget@gmail.com>]

From: Philippe Blain <levraiphilippeblain@gmail.com>

The completion code can be told to use a particular completion for
aliases that shell out by using ': git <cmd> ;' as the first command of
the alias. This only works if <cmd> and the semicolon are separated by a
space. The examples have that space but it's not clear if it's just for
style or if it's mandatory.

Explicitely mention it.

 # completion style.  For example '!f() { : git commit ; ... }; f' will
 # tell the completion to use commit completion.  This also works with aliases
 # of form "!sh -c '...'".  For example, "!sh -c ': git commit ; ... '".
+# Be sure to add a space between the command name and the ';'.
 #
 # If you have a command that is not part of git, but you would still
 # like completion, you can use __git_complete:
