[committed] gcov-tool: Use subcommand rather than sub-command in function comments

[Jakub Jelinek via Gcc-patches]

Hi!

Follow-up to the recently committed fix of fixing the "subcomand" typos
in diagnostics.

Committed to trunk as obvious.

        * gcov-tool.cc (do_merge, do_merge_stream, do_rewrite, do_overlap):
        Use subcommand rather than sub-command in function comments.
