"alias" command has problems

[Elaine Meng]

I don't know if these are all connected or separate problems, so that's why I'm reporting them together.

(a) space is stripped from log, e.g. typing
alias colh color helix $1 targ c
...gives Log:
aliascolh color helix $1 targ c

(b) then "alias list" gives traceback ending in
IndexError: string index out of range
... however, I can use the alias, e.g. "colh blue" works on my structure

(c) "alias delete" also gives traceback ending in UnboundLocalError: local variable 'word_info' referenced before assignment
... and apparently deletes all the aliases, although in the revised design it should require the argument "all" or the name of a specific alias.

I'm inferring that it deletes them all because "colh" no longer works.

Fixed (b), still looking for (a).

Don't get a backtrace for (c). Currently 'alias delete', by itself, deletes all aliases. Requiring the keyword all is better, so I'll do that too.

(c) was a side-effect of (b).

(a) is now fixed too. Bug was with consuming whitespace for a short command of a multiword command.
