Possible to provide alternate delimiter for kibana style?

[ghukill]

Currently, when the Kibana style is flagged with -k, the delimiter used is a comma , e.g.:

History,Fiction

However, this presents a problem when other columns may have commas as well, resulting in a situation where splitting on comma is not a viable option as you may split kibana-style cells, or strings that contain commas.

Curious, might it be possible to provide a delimiter character -- like pipe | -- that could be used instead?
