I cant decide if this is a bug or a feature, but this trips me up at least once a day. This example is sort of indicative of the majority of interface errors I run across with fish, having come from bash.

This command has a * in it, which has a slightly different series of consequences in this context for fish than for bash, so I hit this error:

> rake resque:work QUEUE=* COUNT=1 VERBOSE=1
fish: No matches for wildcard 'QUEUE=*'.
rake resque:work QUEUE=* COUNT=1 VERBOSE=1
                    ^

As a result, I up-arrow, left-arrow over, and insert a backslash:

> rake resque:work QUEUE=\* COUNT=1 VERBOSE=1

With my cursor still positioned on the * after the backslash, I hit enter expecting the command to run. Instead, the query editor splits my line:

> rake resque:work QUEUE=\
   * COUNT=1 VERBOSE=1

So, in order to get the command to run, I have to hit ^e or End before hitting enter.

As I said, I'm not entirely sure if this is expected behavior or a bug involving the editor. My instinct says probably the latter.
