isearch-forward accepts non-alphanumeric keys as input

[Jake Peck]

Stumbled on this one on accident...

<alt-x> isearch-forward

This asks for input. Arrow keys are accepted as input, using their English names as the input, i.e. 'Down', 'Up', etc.

It appears to also work with 'Home', 'PgUp', 'PgDown', etc. 'Home' was particularly interesting, as it actually found a copy of the string 'home'. Very confusing behavior...

Here's the output from the log while I was playing with this:
