Can you try figuring out if this actually works? I tried here and it
doesn't, its an area we took "for free" when we copied the initial
codebase from git.git, but I never looked at this area that much, now
that I try:

[acme@...et linux]$ perf help
Config with no key for man viewer: childrenError: wrong config key-value pair top.children=true
[acme@...et linux]$ 

Unsure if this is something that got broken by the 'perf config'
patches, Taeung?
