readdlm trailing whitespace

[visr]

The default readdlm now treats multiple whitespace separators as one, and ignores leading and trailing whitespace. But this seems not to be the case for trailing whitespace after the last data line.

Hence these work:

readdlm(IOBuffer("  1  2  \n  3  4  "))
readdlm(IOBuffer("  1  2  \n  3  4\n"))

However if I put any whitespace directly before or after the final \n of the second example, I get the following error:

readdlm(IOBuffer("  1  2  \n  3  4 \n"))
ERROR: BoundsError()
 in dlm_offsets at datafmt.jl:201

Therefore a delimited file ending with \r\n will fail, which was my use case. But perhaps in general all trailing whitespace should be allowed and ignored?
