break out of nested `if`

[Peng Yu]

Hi,

`break n` can break out of nested `for`. But sometimes it would be
convenient to break from nested `if`, which does not seem to be an
available feature in bash.

One walkaround is to put the nested `if` in a function and use return
to break from the nested if. But this is not very convenient, as an
extra function must be defined.

Is there a better walkaround to this problem? Thanks.
