Follow-up Comment #4, patch #8593 (project octave):

Thanks for the heads up Philip. 

I had to spend some time getting octave running again after a new xilinx
install hosed my octave install (fragile library dependancies), so I could run
a quick comparison test.

So just FYI, my code runs significantly slower than csv2cell(). On a test CSV
file I found that csv2cell() parsed in 0.016 seconds and read_dlm_esc() parsed
in 0.292 seconds. However, read_dlm_read() will handle lines with a variable
number of fields, which I required for the project I was working on. So, the
good news is that it wasn't completely wasted effort.

I'll keep my github repo active, just incase anyone finds it useful.

Also a heads up to anyone that uses the read_dlm_esc() code. I took a quick
look at it again, and the starting column has not been implemented yet. I have
a place holder parameter, but no functionality for it.

As for maybe adding to csv2cell(), I'll have to see how my schedule works out
in the next year or so.
