This version is basically OK.

	* gdbarch.sh (software_single_step): Change the return type
	from void to int and reformatted some comments to <= 80
	columns.

	* alpha-tdep.h (alpha_software_single_step): Likewise.
	* arm-tdep.c (arm_software_single_step): Likewise.

... et cetera.  No need to repeat.

Note, part of this explanatory comment vanished because we don't put
"why" in ChangeLogs.  This is the sort of thing that one ought to know
when working with the code.  Therefore it should be a comment in the
code.  Please describe the return value in gdbarch.sh.

Thanks!
