Subject: bitstream: Remove pointless variable "code_prefix2".
X-Git-Tag: v0.5.3~17^2~3
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=336b36768ffc8ec1945ed8dcf235fd2a9462c967

bitstream: Remove pointless variable "code_prefix2".

This variable is only used at one place. Using the computed value
directly in the conditional allows to get rid of it.
