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

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.

On what operating system is this?  On Unix/Linux you should be using
options(browser="opera").  On Windows/Mac you can't set the
browser
anyway.

See the requirements for a browser in the details under ?help.start.
Neither of those (nor Netscape 6.1) worked when I tried them with -remote.

I don't think it is a bug in R but I have expanded the documentation.

Please do use the bug.report() function, as critical information is
missing from this report.

I am sorry not having looked carefully on the documentation. But the
first thing I do is to launch help.start() and be stuck with an
inexistent browser. I have imagined that help.start(browser="opera")
would set the browser to opera, but I am wrong and the browser must be
set by options(browser="opera"), a feature which I am not aware of.
Nevertheless, I find this rather confusing for a new user: if
options(browser="opera") should always be used to set the browser,
then the argument browser="opera" in help.start would never be needed.

I rarely used R with remote display, so it is not a concern for me.
But indeed, there is no support for Java in Opera under Linux. I am not
aware that the search engine (in R ?) need Java support. Hopefully
this support will be added in later version of Opera.

My point is that if one launches help.start(browser="foo"), it means
that one would like to use foo as browser, so default browser should
be set to foo.
