[Evolution-hackers] Placing of goto labels

[Milan Crha <mcrha redhat com>]

        Hi,
I'm wondering how to write goto labels, and I'd like to ask how other
projects do it. The thing is not whether to use 'goto' or not, but how
to write goto labels and do not lose on it. I realized that the thing
one can lose is with diff generation, including 'git diff', if the label
is placed at the very beginning of the line, thus I begun to use one
space to avoid this some time ago. As an example, this is after two
changes below goto labels in two files:

-------------------------------------------------

Both has a goto label above the change, but only the first shows
the function name in which the change was done, while with the second
one can only guess. (Note that in evolution code the most common label
is 'exit').

What's the usual way for goto labels in other projects?
Would it make sense to write labels 'one-space indented'?

        Bye,
