Bug#366789: bashism in tex-common.config: arith: syntax error "usercount++"

[Fumitoshi UKAI <ukai@debian.or.jp>]

Package: tex-common
Version: 0.22

tex-common.config failed by
/tmp/tex-common.config.82573: 163: arith: syntax error: "usercount++"

at line 121, there are
      : $((usercount++))
but it is bashism.

% bash
$ usercount=0
$ : $((usercount++))
$ exit
% dash
$ usercount=0
$ : $((usercount++))
dash: arith: syntax error: "usercount++"
$

I think it should be written as
	usercount=$(($usercount+1))
