help: indicate help omitting if help document is not fully displayed

Before this patch, there is no information about whether help document
is fully displayed or not.

So, some users seem to misunderstand "-v" for "hg help" just as "the
option to show list of global options": experience on "hg help -v" for
some commands not containing verbose containers may strengthen this
misunderstanding.

Such users have less opportunity for noticing omitted help document,
and this may cause insufficient understanding about Mercurial.

This patch indicates help omitting, if help document is not fully
displayed.

For command help, the message below is displayed at the end of help
output, if help document is not fully displayed:

    use "hg -v help xxxx" to show more complete help and the global
    options

and otherwise:

    use "hg -v help xxxx" to show the global options

For topics and extensions help, the message below is displayed, only
if help document is not fully displayed:

    use "hg help -v xxxx" to show more complete help

This allows users to know whether there is any omitted information or
not exactly, and can trigger "hg help -v" invocation.

This patch causes formatting help document twice, to switch messages
one for omitted help, and another for not omitted. This decreases
performance of help document formatting, but it is not mainly focused
at help command invocation, so this wouldn't become problem.
