"Single quotes (') and double quotes (") can be used to quote strings
which contain spaces or other special characters."

Spaces always need quoting. folder-hook has two arguments regexp and
command. Both need quoting if they contain spaces.
Usage: folder-hook [!]regexp command
             /----------        |
            / |-----------------------|
folder-hook . set index_format="%F %C" 
so
folder-hook . "set index_format=[value]"

And since you need quotes for the value of
index_format (it contains spaces again) too, you need two levels of
quoting. This is not at all surprising, is it?

folder-hook . 'set index_format="%F %c"'

If you feel, the manual needs improvement, send a patch to mutt-dev. Any
help with improving docs is appreciated. Note: If possible please
directly patch manual.xml.head which is in doc-book format.

HTH,

Michael
