Thanks for multiple file types

According to this post - scroll down to "CCleaner v2.29"

Multiple File Types in one Include/Exclude entry

Prior to CCleaner v2.29, if you wanted to specify file types in
CCleaner’s INI file using Include or Exclude, you had to specify
each file type on a separate line. This had the effect of slowing
CCleaner down, since it had to run multiple scans. With v2.29, you
can now specify multiple file types within a single Include or
Exclude line. Here’s the syntax:

IncludeX=TYPE|Path|extension[;extension][|RECURSE]

This works in winapp2.ini as well.

Try this syntax:

FileKeyx=path|file1.ext;file2.ext

Since the blog post doesn't specify I guess I should ask

if this is a supported use of this feature.
