show: make template option actually show up in help
Previously, the --template/-T option didn't show up in help because it's marked
as experimental. It's not really experimental for show, and its quite important
for show's funcationality, so let's make sure it always shows up.

No arguments shows available views
$ hg init empty
$ cd empty
$ hg show
available views:
bookmarks -- bookmarks and their associated changeset
underway -- changesets that aren't finished
abort: no view requested
(use "hg show VIEW" to choose a view)
[255]
`hg help show` prints available views
$ hg help show
hg show VIEW
show various repository information
A requested view of repository data is displayed.
If no view is requested, the list of available views is shown and the
command aborts.
Note:
There are no backwards compatibility guarantees for the output of this
command. Output may change in any future Mercurial release.
Consumers wanting stable command output should specify a template via
"-T/--template".
List of available views:
bookmarks bookmarks and their associated changeset
underway changesets that aren't finished
(use 'hg help -e show' to show help for the show extension)
options:
-T --template TEMPLATE display with template
(some details hidden, use --verbose to show complete help)
Unknown view prints error
$ hg show badview
abort: unknown view: badview
(run "hg show" to see available views)

HGPLAIN results in abort
$ HGPLAIN=1 hg show bookmarks
abort: must specify a template in plain mode
(invoke with -T/--template to control output format)
[255]
But not if a template is specified
$ HGPLAIN=1 hg show bookmarks -T '{bookmark}\n'
(no bookmarks set)
$ cd ..
bookmarks view with no bookmarks prints empty message
$ hg init books
$ cd books
$ touch f0
$ hg -q commit -A -m initial
$ hg show bookmarks
(no bookmarks set)
bookmarks view shows bookmarks in an aligned table
$ echo book1 > f0
$ hg commit -m 'commit for book1'
$ echo book2 > f0
$ hg commit -m 'commit for book2'
$ hg bookmark -r 1 book1
$ hg bookmark a-longer-bookmark
$ hg show bookmarks
* a-longer-bookmark 7b570
book1 b757f
A custom bookmarks template works
$ hg show bookmarks -T '{node} {bookmark} {active}\n'
7b5709ab64cbc34da9b4367b64afff47f2c4ee83 a-longer-bookmark True
b757f780b8ffd71267c6ccb32e0882d9d32a8cc0 book1 False
bookmarks JSON works
$ hg show bookmarks -T json
[
{
"active": true,
"bookmark": "a-longer-bookmark",
"longestbookmarklen": 17,
"node": "7b5709ab64cbc34da9b4367b64afff47f2c4ee83"
},
{
"active": false,
"bookmark": "book1",
"longestbookmarklen": 17,
"node": "b757f780b8ffd71267c6ccb32e0882d9d32a8cc0"
}
]
JSON works with no bookmarks
$ hg book -d a-longer-bookmark
$ hg book -d book1
$ hg show bookmarks -T json
[
]
$ cd ..
