Dear R-users,

It is my understanding that cat(shQuote(a.string)) should print the origintal a.string. Is this right?
I am not sure cat() correctly prints strings which are generated by triple-shQuote():

> shQuote(shQuote("a"))
[1] "\"\\\"a\\\"\""
> cat(shQuote(shQuote(shQuote("a"))), '\n')
"\"\\"a\\"\<file://\\"a\\"\>""
As you can see the latter string has fewer quoting '\' than the former.
cat() of double shQuote works as expected:

> shQuote("a")
[1] "\"a\""
> cat(shQuote(shQuote("a")), '\n')
"\"a\""
> version
               _
platform       i386-pc-mingw32
arch           i386
os             mingw32
system         i386, mingw32
status
major          2

svn rev        43537
language       R
version.string R version 2.6.1 (2007-11-26)
Am I missing something?

Thanks,
Vadim
