Subject: bitstream: Kill pointless variable "symbol".
X-Git-Tag: v0.5.3~17^2~5
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=b35708a83afe82b18251d53343519dd41e6e80f6;hp=179502e8ff1884776ff9c7ee20ff5e2e8ce03072

bitstream: Kill pointless variable "symbol".

It is just a copy of the loop index i. Since i is never modified
we may simply use i instead.
