icalendar "description" suggestion

[Tom Tromey <tromey@redhat.com>]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


Lately I've been using icalendar-import-buffer to convert a Zimbra
calendar to Emacs format.

This works pretty well, except that Zimbra puts the string
"*~*~*~*~*~*~*~*~*~*" into the DESCRIPTION field.  I'm not exactly
sure where this comes from, though a Zimbra bug report suggests that
perhaps it is an Outlook thing:

http://bugzilla.zimbra.com/show_bug.cgi?id=6071

(see comment #1)

It would be nice if icalendar-import-buffer understood this convention
and deleted any text before the magic string from the description.

More generally it would be nice to be able to exert more control the
over formatting of the description than is provided by a format string
like icalendar-import-format-description.  For instance, in my case I
want to compact sequences of newlines into a single newline.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/22.0.990/etc/DEBUG for instructions.
