A matter of opinion :) I tend to think goto is special enough to
warrant column 1 unconditionally. It is special, so it draws additional
attention over and above case labels.
I and others have been tripped up when programmers "hide" goto
statements among regular statements.
IMO goto warrants a big flashing "notice me" sign.
Hmmm, perhaps.
So, it seems that we can reach an agreement. Any other comments or
suggestions?
One more -- I absolutely agree with Jeff that goto should stand out as best as
possible but I think that's actually more so when they're indented 2 columns.
Have been working on a legacy CD-ROM driver lately and puting "out:" labels at 2
spaces started out as a personal style preference of Pekka Enberg (I used to put
them at 0) but has grown on me. It makes them clearly fall inside the function,
not being aligned at the same level as the next function header, which makes
for the "lowest effort visual scan" of all I feel. One is just too little for
that, more than 2 is too much...
Here's the last version that was posted:

It gets a little different visually when labels are mostly longer than a simple
"out" or "again", or "error" or something like that but if someone's going to
try to pin down the label style, I'd like the freedom to have two spaces in
front of them...
