Line feeds within commands provided to GNU Parallel appear to prevent --colsep from functioning.

Failing case :

address@hidden:~] parallel --dry-run --colsep '\t' "
echo {1} {2}
" :::: <(perl -e 'printf "A\tBC\tD"')

echo {1} {2}
 A BC D

Passing case:

address@hidden:~] parallel --dry-run --colsep '\t' "echo {1} {2}" :::: <(perl -e 'printf "A\tBC\tD"')
echo A BC

Description:

It appears that --colsep, when used with a command containing line feeds, ceases to function. It behaves as though no input substitutions were requested and therefore adds the default substitution, {}, at the end of the command. Am I perhaps doing something incorrect?

Thanks,
