mh-sub-folders

mh-sub-folders is an autoloaded Lisp function in `mh-utils.el'.

(mh-sub-folders FOLDER &optional ADD-TRAILING-SLASH-FLAG)

Find the subfolders of FOLDER.
The function avoids running folders unnecessarily by caching the
results of the actual folders call.

If optional argument ADD-TRAILING-SLASH-FLAG is non-nil then a
slash is added to each of the sub-folder names that may have
nested folders within them.
