I noticed in Info mode pressing "i" to do an index search for a C
function often doesn't leave point at the right place in the node.

For example in the glibc manual, "i write" leaves point with the
mention of `write' at the top of the node, rather than the "Function"
definition part.


I think the regexp in Info-find-index-name doesn't account for a
return type with a function definition.  Perhaps a looser search could
be added, per below.
