Update wording:

< * Allow building with directories containing spaces
> * Allow building in directories containing spaces
<   There are two capabilities here, first the ability to build from a
<   source directory that contains spaces, and second the ability to install
<   into a directory that contains spaces.  The first is probably not
<   possible because 'gmake' and other compiler tools do not fully support
<   spaces in path names.  The second is possible with proper quoting in
<   the makefiles.  Because PostgreSQL supports relocatable installs, it
<   is possible to install into a directory that doesn't contain spaces and
<   then copy the install to a directory with spaces.
>   This is probably not possible because 'gmake' and other compiler tools
>   do not fully support quoting of paths with spaces.
>
> * Allow installing to directories containing spaces
>
>   This is possible if proper quoting is added to the makefiles for the
>   install targets.  Because PostgreSQL supports relocatable installs, it
>   is already possible to install into a directory that doesn't contain
>   spaces and then copy the install to a directory with spaces.
