[Rd] prompt () and backticks for default arguments

[Claudia Beleites]

Dear all,

I just noticed, that prompt () looses backticks that protect default arguments:

f <- function (FUN = `*`) {}

cat (prompt (f, NA)$usage)

yields:
\usage{ f(FUN = *) } %- maybe also 'usage' for other objects documented here.
without the backticks, which is of course found by R CMD check as syntax error.

While this is easily fixed if the .Rd is further edited manually, I stumbled 
over it using the automated .Rd generation with inlinedocs - in this combination 
it is very inconvenient.

Any suggestions?

All the best,

Claudia
