Ethan Atkins c7ec97d18f Rework multi parser to exclude 'alias'
There have been numerous issues with the multi parser incorrectly
splitting commands like `alias foo = ; bar` into
`"alias foo =" :: "bar" :: Nil`. To fix this, I update the multi parser
implementation to accept a list of commands that cannot be part of a
multi command. For now, the only excluded command is "alias", but if
other issues come up, we can add more. I also thought about adding a
system property for excluding more commands but it didn't seem worth the
maintenance cost at this point.

In addition to adding a filter for the excluded commands, I also
reworked the multi parser so that I think its more clear (and should
hopefully have more predictable performance). I changed the cmdPart
parser to accept empty strings. Prior to this, the parser explicitly
handled the non-leading semicolon and leading semicolon cases
separately. With the relaxed cmdPart, we can handle both cases with a
single parser. We just have to strip any empty commands at the beginning
or end of the command list.
