stripwhitespace=true not removing trailing white space?

[biona001]

On CSV v0.10.9, reading this file: https://bitbucket.org/nygcresearch/ldetect-data/src/master/EUR/fourier_ls-all.bed
with stripwhitespace=true doesn't seem to work as intended

julia> using CSV, DataFrames
julia> df = CSV.read("fourier_ls-all.bed", DataFrame, stripwhitespace=true)
julia> df[1, 1]
"chr1 "

Column 1 still has extra trailing white space?

It seems like stripwhitespace does not work when the delimiter is itself a whitespace character.

Proof of concept:

julia> csv = "a\tb\tc  \n1\t2\t3"
"a\tb\tc  \n1\t2\t3"

julia> CSV.File(IOBuffer(csv), delim='\t', stripwhitespace=true)
1-element CSV.File:
 CSV.Row: (a = 1, b = 2, var"c  " = 3)
