Return information on a label. On input `data` is an object with the following fields:
* `label`: The label to return information on.
* `lang`: The language of the label. Must be specified unless `for_doc` is given.
* `term_mode`: If true, the label was invoked using {{tl|tlb}}; otherwise, {{tl|lb}}.
* `for_doc`: Data is being fetched for documentation purposes. This causes the raw categories returned in
`categories` to be formatted for documentation display.
* `nocat`: If true, don't add the label to any categories.
* `already_seen`: An object used to track labels already seen, so they aren't displayed twice. Tracking is according
to the display form of the label, so if two labels have the same display form, the second one won't be displayed
(but its categories will still be added). If `already_seen` is {nil}, this tracking doesn't happen.
The return value is an object with the following fields:
* `raw_label`: The original label that was passed in (without any preceding exclamation point).
* `canonical`: If the label is an alias, this contains the canonical name of the label; otherwise it will be {nil}.
* `label`: The display form of the label.
* `categories`: A list of the categories to add the label to; an empty list of `nocat` was specified.
* `formatted_categories`: A string containing the formatted categories; an empty string if `nocat` or `for_doc` was
specified or if
* `deprecated`: True if the label is deprecated.
* `display_raw_label`: If true, the label was preceded by ! to indicate that the raw label should be displayed
rather than the canonical form.
* `recognized`: If true, the label was found in some module.
* `data`: The data structure for the label, as fetched from the label modules. For unrecognized labels, this will
be an empty object.

Format one or more already-processed labels for display and categorization. "Already-processed" means that
{get_label_info()} or {get_label_list_info()} has been called on the raw labels to convert them into objects containing
information on how to display and categorize the labels. This is a lower-level alternative to {show_labels()} and is
meant for modules such as [[Module:alternative forms]], [[Module:quote]] and [[Module:etymology/templates/descendant]]
that support displaying labels along with some other information.
On input `data` is an object with the following fields:
* `labels`: List of the label objects to format, in the format returned by {get_label_info()}.
* `lang`: The language of the labels.
* `term_mode`: If true, the label was invoked using {{tl|tlb}}; otherwise, {{tl|lb}}. This only affects categorization.
* `sort`: Sort key for categorization.
* `already_seen`: An object used to track labels already seen, so they aren't displayed twice, as documented in
{get_label_info()}. To enable this, set this to an empty object. If `already_seen` is {nil}, this tracking doesn't
happen, meaning if the same label appears twice, it will be displayed twice.
* `open`: Open bracket or parenthesis to display before the concatenated labels. If specified, it is wrapped in the
{"ib-brac"} CSS class. If {nil}, no open bracket is displayed.
* `close`: Close bracket or parenthesis to display after the concatenated labels. If specified, it is wrapped in the
{"ib-brac"} CSS class. If {nil}, no close bracket is displayed.
* `no_ib_content`: By default, the concatenated formatted labels inside of the open/close brackets are wrapped in the
{"ib-content"} CSS class. Specify this to suppress this wrapping.
Return value is a string containing the contenated labels, optionally surrounded by open/close brackets or parentheses.
Normally, labels are separated by comma-space sequences, but this may be suppressed for certain labels. If `nocat`
wasn't given to {get_label_info() or get_label_list_info()}, the label objects will contain formatted categories in
them, which will be inserted into the returned text. The concatenated text inside of the open/close brackets is normally
wrapped in the {"ib-content"} CSS class, but this can be suppressed, as mentioned above.

* `lang`: The language of the labels.
* `term_mode`: If true, the label was invoked using {{tl|tlb}}; otherwise, {{tl|lb}}.
* `nocat`: If true, don't add the label to any categories.
* `sort`: Sort key for categorization.
* `no_track_already_seen`: Don't track already-seen labels. If not specified, already-seen labels are not displayed
again, but still categorize. See the documentation of {get_label_info()}.
* `open`: Open bracket or parenthesis to display before the concatenated labels. If {nil}, defaults to an open
parenthesis. Set to {false} to disable.
* `close`: Close bracket or parenthesis to display after the concatenated labels. If {nil}, defaults to a close
parenthesis. Set to {false} to disable.
Compared with {format_processed_labels()}, this function has the following differences:
# The labels specified in `labels` are raw labels (i.e. strings) rather than formatted objects.
# The open and close brackets default to parentheses ("round brackets") rather than not being displayed by default.
# Tracking of already-seen labels is enabled unless explicitly turned off using `no_track_already_seen`.
# The entire formatted result is wrapped in the {"usage-label-sense"} CSS class (or {"usage-label-term"} if `term_mode`
is specified).
