replacement ? or help fails on ::: (triple colon)

If the devools_shims environment is on the search path (after running load_all, or check()), a drop-in replacement of ? and help is used, but this fails on calling ?:::`` or help(:::`)`, both throwing
`Error in getNamespace(ns) : attempt to use zero-length variable name`

Especially annoying because when running check() on some code that includes the triple colon, the NOTE warning you about its use ends with See the note in ?::: about the use of this operator.

Details about my setup:
OSX High Sierra, 10.13.5 (x86_64-apple-darwin15.6.0)
R version 3.5.0
devtools 1.13.5 & 1.13.5.9000 & 1.13.6 (I updated after first encounter)
Occurs both in RStudio 1.1.453 and R from a bash-prompt

And so a reprex:

# Be in a package directory
library(devtools)
check()
?`:::`

This issue was moved by jimhester from r-lib/devtools#1806.

That's quick! Thanks
