[support] Removing Modules

[Brian Choc]

Greetings,

I've not removed any modules in awhile, so maybe something has 
changed in the last few versions.  However, when I disable, 
(possibly) uninstall, and then delete the /www/sites/all/modules/XX 
module folder, in 5.7, the module is not being removed from the list 
at /admin/build/modules.  In some cases, the modules are marked 
"(missing)" in red, in other case not.  Regardless, they're not going 
away, but in my memory they should be.

Any thoughts on what I might do to completely remove modules?

Brian
