SF: PC: bpcp -r not working as expected

[iondev33]

bpcp does not seem to work in recursive mode. There are no examples nor tests describing this mode of operation.
example: bpcp -r ./data/* 2:./data
It is not clear if slashes are required or not, if wildcard char is required or not...

bpcp -r data 2:./data returns a bunch of errors such as:
bpcp: data/data6.dat--No such file or directory [although this file does exist]

PC: Note: I only tested on 3.7.0 but I am guessing it also applies to 4.x
