[Rd] problem with help.start() in R (PR#1156)

[Dinh-Tuan.Pham@imag.fr]

       Hi,
       The function help.start() assume that the brower is netscape
which is no longer the dominant brower in used. I am using now opera
and other use mozilla or Microsoft IE. I can always type
help.start(browser="opera"), but it is not convenience: I would like
to be able to set the default brwsernone for all. But the real bug is
that even after launching help.start(browser="opera"), other help
commands, help(help), say, still send the "help page" to netscape. Here
is what I get

> help.start(browser="opera")
If opera  is already running,   it is *not* restarted,
 and you must switch to its window.
Otherwise, be patient..
> help(help)          
help() for help  is shown in browser netscape ...
Use      help( help , htmlhelp=FALSE)
or       options(htmlhelp = FALSE)
to revert.
> sh: netscape: command not found

Please correct this bug.
