[PATCH] help: replace underlining "help -a" headers using hyphens with a blank line

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

We want the underline to align with the text above, for example:

This is a header
----------------
content...

Unfortunately calculating text length could get complicated because
the text could be in any charset in translated Git. Avoid it and print
a blank line (i.e. charset neutral) instead. Readability is not
affected much. After the change we get:

This is a header:

content...

While at it, give translators more context to translate, e.g.
e.g.  "git commands available..." instead of "%s available..."

 And it does _not_ assume the translated text is in utf-8.

 And thanks Junio for fixing the other nit before merging the seriess
 to next. I should have read and reacted on these posts yesterday.
