[File] Negative indexing breaks search

[Toni Ruottu]

I do not understand how negative indexing and search interact with each
other. I created a file that contains a single line with alphabets from "a"
to "z". It seems that after I have performed negative indexing, I can no
longer search reliably.

The search in the following magic does not work.

0       string          abc             abc
>-4     string          xyz             xyz
>0      search          opq             opq

However, the search does work if I reverse the order.

0       string          abc             abc
>0      search          opq             opq
>-4     string          xyz             xyz

Is this expected behaviour or have I encountered a bug?
