bug#62721: 30.0.50; EUDC: stop adding a wildcard to LDAP searches

[Fabrice Bauzac-Stehly]

Hello,

Sorry, I have not put sufficient information in my initial message.  In
my case, I'm using eudc-query-form, where I know I can add wildcards to
the fields if I want.  My complaint is about the fact that a wildcard is
imposed on me in this case, with annoying consequences.  Thanks to your
message, I understand though that this automatic wildcard may be useful
in other contexts where `eudc-ldap-format-query-as-rfc1558' is called.

Customizing `eudc-ldap-no-wildcard-attributes' would work in the sense
that I could disable the wildcards in all cases, but I suspect this
solution is not ideal as it would also disable it in the case of
eudc-expand-inline where (as I understand from your message) it would
actually be useful.

I think that in the case of eudc-query-form, no wildcard should ever be
added.  What do you think?  Should we pass some parameter so that
eudc-ldap-format-query-as-rfc1558 knows what to do?

Thanks!
