The git command now uses --git-dir instead of --work-tree.
Using --work-tree won't work if you are inside another Git repository.

`brew fetch --deps` will also cache the dependencies of any listed formulae.

If a formula is given, it will be checked for missing deps.
The formula does not have to be installed first.

Without a formula list, still checks all installed brews.

-n means 'natural order' instead of alpha-order, and will show
the order in which the deps will be installed.

Using 'sudo' should not be required to install npm, and isn't if the
user has used the default Homebrew installation process.

When the name of a new formula can't be autodetected, it defaults to the empty
string. When it then gets read from user input later on, the new name is used
but the formula path, based on the name, stays empty.

This change sets the path after a new name was read.

Apaprently both expat.framework and libexpat.framework exist
and interfere with CMake.

The Fortran regex only allowed for trailing whitespace after:

    depends_on 'gfortran'

This missed conditional dependencies, such as:

    depends_on 'gfortran' if something?

Such a dependency was present in the NetCDF formula.
