a simple little script to help changing `select *` into something more useful

say you have a table with a lot of columns
and you want to see some of them, but you're not sure which ones
do a `select *`, then copy the huge long column list, then do `winnow_cols '<paste>'`
it will take out the extranneous whitespace, turn the pipe separators into commas, then fire up vi on the results
simply remove the cols you don't like, and/or rearrange to taste
save and exit, then copy the resulting output back to your query
voila! you've easily turned your `select *` into something actually useful
ever so tired of having to write Perl to find out how long an MP3 is from the command line ...
like I was _really_ going to type `make tail-error-stg` ...
