Hi all,

I was looking into some area where I could contribute and ended up writing
unit
tests for `delim-col.el' and adding the lexical-binding header.

I wasn't inclined to convert the code in delim-col.el to actually take
advantage
of lexical bindings, but it compiles and runs fine with just naively adding
the
header.

Please let me know what you think or if I've made any obvious mistakes.

Thanks,
Stefan Kangas

PS. Since this patch is longer than 15 lines, I have initiated the copyright
assignment process.  It wasn't obvious if this should be done before or
after
mailing this list.
