* Use PathUnescape instead of QueryUnescape when working with branch names
Currently branch names with a '+' fail in certain situations because
QueryUnescape replaces the + character with a blank space.
Using PathUnescape should be better since it is defined as:
// PathUnescape is identical to QueryUnescape except that it does not
// unescape '+' to ' ' (space).
Fixes#6333
* Change error to match new function name
* Add new util function PathEscapeSegments
This function simply runs PathEscape on each segment of a path without
touching the forward slash itself. We want to use this instead of
PathEscape/QueryEscape in most cases because a forward slash is a valid name for a
branch etc... and we don't want that escaped in a URL.
Putting this in new file url.go and also moving a couple similar
functions into that file as well.
* Use EscapePathSegments where appropriate
Replace various uses of EscapePath/EscapeQuery with new
EscapePathSegments. Also remove uncessary uses of various
escape/unescape functions when the text had already been escaped or was
not escaped.
