[PATCH] gendocs.sh

[Sergey Poznyakoff]

Hello,

I propose the attached patch to gendoc.sh utility. 

The reason for evaluating $cmd prior to its execution is that  otherwise
it is impossible to pass quoted arguments to texi2dvi. For example, in
GNU Anubis we use the following Makefile snippet:

manual:
        TEXINPUTS=$(srcdir):$(top_srcdir)/build:$(TEXINPUTS) \
        MAKEINFO="$(MAKEINFO) $(MAKEINFOFLAGS)" \
        TEXI2DVI="$(TEXI2DVI) -t @finalout -t '@set $(RENDITION)' -E" \
        $(GENDOCS) anubis 'GNU Anubis manual'

Without the proposed change option "-t '@set $(RENDITION)'" is passed as
two arguments.

I suspect that all other invocations of `$cmd' should also be made via
`eval', although I did not check this yet.

Regards,
Sergey
