manifest: add some documentation to _lazymanifest python code
It was not particularly easy figuring out the design of this class and keeping

pycompat,
util,

def main(argv):
enc = util.urlreq.quote(pycompat.sysbytes(argv[1]))
if pycompat.iswindows:
fmt = 'file:///%s'
else:
fmt = 'file://%s'
print(fmt % pycompat.sysstr(enc))
