more warnings and cleanups

Here are some more patches in the same vein.

Patches 1-4 fix style problems noticed with make CC="c89 -pedantic" (mostly concerning the -pedantic rather than the c89).

Patch 5 updates fast-import.c (and everyone else) to put braces on the same line as "struct foo" --- the waste of space had bothered me every time I hacked on fast-import.c so now is my chance. :)

Patches 6-8 factor out some new functions to un-indent code a little. The indented code was discovered in changing

	struct pretty_print_ctx ctx = {0};

into something more verbose to appease gcc -Wmissing-field-initializers, which probably wasn't a good idea after all. :) But the by-product is nice.

Jonathan Nieder (8):
enums: omit trailing comma for portability
compat: make gcc bswap an inline function
svn-fe: do not use "return" for tail call returning void
vcs-svn: remove spurious semicolons
standardize brace placement in struct definitions
branch: split off function that writes tracking info and commit
subject
cherry: split off function to print output lines
diff --submodule: split into bite-sized pieces
