- is frowned upon. A gray area is when the statement extends
- over a few lines, and/or you have a lengthy comment atop of
- it. Also, like in the Linux kernel, if there is a long list
- of "else if" statements, it can make sense to add braces to
- single line blocks.
+ is frowned upon. But there are a few exceptions:
+
+ - When the statement extends over a few lines (e.g., a while loop
+ with an embedded conditional, or a comment). E.g.:
+
+ while (foo) {
+ if (x)
+ one();
+ else
+ two();
+ }
+
+ if (foo) {
+ /*
+ * This one requires some explanation,
+ * so we're better off with braces to make
+ * it obvious that the indentation is correct.
+ */
+ doit();
+ }
+
+ - When there are multiple arms to a conditional and some of them
+ require braces, enclose even a single line block in braces for
+ consistency. E.g.:
+
+ if (foo) {
+ doit();
+ } else {
+ one();
+ two();
+ three();
+ }
- We try to avoid assignments in the condition of an "if" statement.

When retrieving svn commits into Git (as part of 'fetch', 'rebase', or
'dcommit' operations), look for the first `From:` or `Signed-off-by:` line
in the log message and use that as the author string.

--add-author-from::
When committing to svn from Git (as part of 'commit-diff', 'set-tree' or 'dcommit'
operations), if the existing log message doesn't already have a
`From:` or `Signed-off-by:` line, append a `From:` line based on the
Git commit's author string. If you use this, then `--use-log-author`
will retrieve a valid author string for all commits.
