completion: improve doc for complex aliases

Browse Source 
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, since if the space is missing __git_aliased_command returns (for
example) 'checkout;' instead of just 'checkout', and then
__git_complete_command fails to find a completion for 'checkout;'.

The examples have that space but it's not clear if it's just for
style or if it's mandatory. Explicitly 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:
