Apparently, all of the members of enum virDomainState have wrong
indentation.

I think this won't work reliably. All you see in the parser is COMMENT
and NAME tokens.
You could only special case on two consecutive comments and then
assign the second to the current member.
Otherwise, what we could do is change the style rules and use the
comma as a separator:
ONE /* short comment for one */,
/* longer comment for two */
TWO,
THREE /* and short for three again */,
That way the association would be unambiguous. But I could imagine
what you're saying - that's ugly... It would require changing all
existing comments.
Another alternative I can think of would be to use a special marker
for "postfix" comments (like doxygen):
ONE, /*< short comment for one */
/* longer comment for two */
TWO,
THREE, /*< and short for three again */
This would also require changing all existing comments, unless we
introduce a special marker for "prefix" comments...
So, having said all that, here's another idea:
--- >8 ----
Subject: [PATCH] docs: Differentiate long and short comments inside enums
Regard a comment containing newline characters as a long comment
associating to the current member, otherwise it's just a short comment
associated with the previous member.
