Invocations of the spec parser used to exit with an error code (245)
in the case where no files were specified. This was considered to be a
useless type of invocation, and the spec parser would print out a help
message.
However, it is perfectly possible for a Gerrit CL to give rise to
invocations like that, e.g., when the CL deletes some files and does
nothing else. Also, it causes no known issues to report a success exit
code (0) in the case where no files are specified, and hence this CL
changes the spec parser accordingly.
