Redundant blank lines when printing -help

[brlin-tw]

Refer the following screenshot:

There are two redundant blank lines before the actual -help content (in 5.2.0 there was only one but now there are two), which is not pretty IMO.

I would suggest keep no blank lines at all or only one blank line, if there's any reason to do so.

@Lin-Buo-Ren this is certainly your preference, but I wonder whether it is universal... maybe...

Wandering back in history, the original tidy creators certainly liked redundant blank lines... and I sort of got used to them, even liked them... over the years some have been eliminated in the pretty print output, but can sometimes be restored by --vertical-space yes, referred to as classic mode in the code, but not all... but maybe not at all relevant here...

You are just referring to -h text...

Back at 5.2.0, 5.4.0 there was only 1... and maybe more important, back in tidy-2000 and tidy-2009 there were none...

So this does feel like redundant blank line creep in help... nothing to do with classic mode...

So, in general, could go for PR #782, a very limited change...

What do others think? Look forward to further feedback... thank...
