bug#2533: 23.0.90; [PATCH] rmail: improve rmail-add/kill-label docstring

[Xavier Maillard <xma@gnu.org>]

When using keys 'a' or 'k' in a `rmail-summary' buffer, it is not
obvious user can type multiple labels as "comma-separated list of
labels". OTOH, it is clearly announced when user wants to
summarize by labels. The patch enclosed tries to clarify this.

Hope that'll help.

ChangeLog proposed:

2009-03-01  Xavier Maillard  <xma@gnu.org>

	* mail/rmailsum.el (rmail-summary-add-label)
	(rmail-summary-kill-label): Fix docstrings. Indicate user can type
	multiple comma-separted list of labels.
