Bug#367566: [exp] Seems to run in an infinite loop when deleting a fold with foldmethod=manual

[Loïc Minier]

Package: vim
Version: 1:7.0-017+1
Severity: minor

        Hi there,

 (Thanks for preparing vim 7, it's amazing!)

 When I opened a changelog.Debian with vim 7, it was all folded by
 default, so I ":set foldmethod=manual" and "zd" to remove the fold, but
 this hogs the CPU to 100%.

 I tried with an extract of the changelog and without zip compression,
 and the bug remains, so I suppose it is a bug, not just something that
 takes long to complete.  "za", "zD" and "zO" work fine.

 ^C stops the CPU consumption and finishes the operation.

   Bye,

PS: attaching my uninteresting .vimrc just in case
