Undefined behavior when multiple functions are matched by the same signature

[ccarpenter04]

As far as I can tell, the behavior for when multiple functions that match the same signature is not specified. For small functions, it's quite common to encounter multiple matches for the same FLIRT signature (especially for small functions).
It would be optimal to be able to specify whether the matches are ignored or alternate behaviors when multiple functions match a single pattern, however documenting the current behavior in the readme would be a step in the right direction.
IDA lets you specify the behavior (the first suggestion) and was the inspiration for this issue.
