#3000: Deleting >50k messages from IMAP boxes fails with Fatal error:
        word too long

 {{{
 Hi,

 I'm trying to delete some 200k messages from a 240k IMAP folder.
 Tagging ~m1-10000 and deleting/expunging works. For larger selections
 (I first tried 200k and then 50k), mutt fails with

 Fatal error: word too long

 and closes the folder.

 Mutt version 1.5.17, both tarball and hg HEAD.

 Christoph
