[PATCH] remove newline characters from the contents of table cells

["Eric Schulte" <schulte.eric@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 357 bytes --]

This patch changes the functionality of orgtbl-to-orgtbl so that it will
remove newline characters from the text of table cells and replace them
with "\n".  This protects the final table from such newlines.

This patch will probably only have any noticeable effect for tables
imported form external files, or from the results of code blocks.
