Subject: command: Make struct command_context->cmd_ptr const.
X-Git-Tag: v0.5.5~51
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=38de4128737b8d86c637d5d0edc7cffd74666bdc;p=paraslash.git

command: Make struct command_context->cmd_ptr const.

The fields of struct server command never need to be modified so they
can be const.
