[PATCH 08/23] xapcmd: simplify {reindex} parameter passing

[Eric Wong <e@yhbt.net>]

No need to localize it, here, since we can just refer to it
in the `$opt' hashref.  Hopefully this improves readability
for others like it does for me.

I sometimes wonder if the concept of a stack in high-level
languages is even necessary...
