"""fix git symlinked files in windows that had been copied from src to dst
Most (all?) of git implementations in windows store a symlink pointing
into the repo as a text file, the text being the relative path to the
file with the real content.
So, in a clone of nikola in windows the symlinked files will have the
wrong content.
The linux usage pattern for those files is 'copy to some dir, then use',
so we inspect after the copy and rewrite the wrong contents.
The goals are:
support running nikola from a clone without installing and without
making dirty the WC.
support install from the WC.
if possible and needed, support running the test suite without making
dirty the WC.
