'''Q.''' ''What's the difference between '''file exists''' and '''[file isfile]'''?''

'''A.''' '''file exists''' returns true (1) for all existing directories and regular files.  '''[file isfile]''' returns true only for existing regular files.

Note: if [[file exists $a]] && ([[file type $a]] == "file") then [[file exists ${a}/]], which seems inconsistent.

In normal usage, it wouldn't bother anyone, but in [VFS] work, there can be a world of difference between a file "$a", a directory "$a", and a file "$a/".  I suspect this stems from [[[file split] a/b]] == {a b} != {a b {}} - 20040613 [CMcC]
