'**2' item works in findfile() but not in globpath()
Erik Falor
work with the globpath() function.
From editing.txt , line 1471:
"The file searching is currently used for the 'path', 'cdpath' and 'tags'
options, for |finddir()| and |findfile()|."
Is there any reason in particular why the +path_extra feature bestows special powers upon these options and functions, but not upon globpath()?

There are two separate pieces of code that expand "**". One is what is
used for 'path' and a few other file-searching operations. This is
implemented in find_file_in_path(). The other is part of the file name
expansion, done with mch_expandpath().
They are not compatible, unfortunately. find_file_in_path() expands
wildcards in the path, but not in the file name. It does handle
"**2"and upwards search. mch_expandpath() expands all wildcards, but
does not support "**2" or upwards search.
Merging the two kinds of wildcard expansion is a lot of work.
