[ESS] "An indirect buffer cannot visit a file."

[Kevin Wright]

At the risk of continuing this thread past it's prime...

I played with the regex more.  Including this line in your .emacs

(add-to-list 'ibuffer-never-show-predicates ".*\\[.*\\]$")

will shorten the ibuffer Buffer List from (while editing Rmd, Rd, and an
ESS help buffer)

cov.Rmd
cov.Rmd[poly-head-tail]
cov.Rmd[r]
*help[R](plot)*
*help[R](plot)*[poly-head-tail]
*help[R](plot)*[R]
beal.Rd
beal.Rd[R]

to

cov.Rmd
*help[R](plot)*
beal.Rd
