Don't send 8 identically titled patches that each change a single line.

Send one patch, with an updated title like:

Subject: [PATCH] jsm_tty: Whitespace neatening

that changes _all_ the whitespace that you believe should be updated.

And ideally, instead of just whitespace changes, the code would be
updated to eliminate the code duplication by using temporaries and a
single line conversion.
