abort git-alias when too many arguments given.

Avoid incorrect usage probably because of the missing quotes, like "git
alias cm checkout master"

This is a good idea.

Maybe we could just print a usage message instead?

Just add a "usage" banner

I'm sorry I didn't just do this straight away. I was thinking we should do it like i.e git rebase does it.

error: unknown option `fsjljksldf'
usage: git rebase [-i] [options] [--exec <cmd>] [--onto <newbase>] [<upstream>] [<branch>]
   or: git rebase [-i] [options] [--exec <cmd>] [--onto <newbase>] --root [<branch>]
   or: git-rebase --continue | --abort | --skip | --edit-todo

etc..

as in

error: too many arguments
usage: git alias                         # list all aliases
  or: git alias <search-pattern>         # show aliases matching pattern
  or: git alias <alias-name> <command>   # alias a command

( I think the comments was nice so I left them in, although git doesn't usually do it that way)

And maybe we should call it <search-pattern>, because it is a regex. Then you can edit the man page to say search-pattern instead of search-term as well.

All right, updated it.
