gnulib-tool dependency printing

[Simon Josefsson]

For a project that has this gnulib-cache.m4 content:

gl_MODULES([
  git-version-gen
  lib-symbol-versions
  maintainer-makefile
  uniconv/u8-strconv-from-locale
  unictype/bidicategory-of
  unictype/category-M
  unictype/category-test
  unictype/joiningtype-of
  uninorm/nfc
  uninorm/u32-normalize
  unistr/u32-cpy-alloc
  unistr/u32-to-u8
  unistr/u8-to-u32
])

The output below is printed when I run 'gnulib-tool --add-import'.  Look
carefully at it.  For example it gives the impression that 'gperf' and
'iconv' are dependencies of 'git-version-gen' which seems bogus.  Also
the first few modules are not directly requested and should probably be
indented under some other module?

Or am I reading the output incorrectly?  I haven't looked at the code
yet because I'm not sure I understand what is intended here.  Generally,
I think it would be nice to print the modules requested (the list above)
in the first indentation, and the recursive dependencies of that module
in second indentation (except for dependencies of modules already
listed, to avoid circular dependencies).
