This change ensures that when exporting `requirements.txt`, local 
direct reference dependencies are exported as uri and not paths.

Resolves: #3189

This reverts commit 37b36f48 as this is no longer required.

I think the "Expanded dependency specification syntax" paragraph added in
commit c94c34c8 was inserted in the wrong place
and cut the note from its corresponding block.

Fixes #2867, the virtual environment found seems to be broken
messages when running in MSYS2. This change detects when in MSYS2
in order to use the bin directory for the virtualenv instead of
Scripts which is normally used in Windows.

This repairs a broken triple-bang note.  Also cleans up a few stray double-newlines and very long lines to match rest of file.

Resolves: #1393
