Heh, this obviously hasn't been exercised much... The issue is that
NAMESPACE contains

exportPattern("^tcl[[:alnum:]]*($|<-)") # skip S3 methods
exportPattern("^tk")

so the tk --> tcl prefix change doesn't automatically work on
functions with a dot in them. tclfile.tail is the only other case that
I can spot.

Best to fix in the obvious way at the current stage, but I wonder
whether it wouldn't have been better just to have tclfile("dir",
myfile) -- or for that matter just let users use the straightforward
tcl("file", "dir", myfile). (Or dirname(myfile) for that matter).
