[PATCH v1 07/45] parse_pathspec: save original pathspec for reporting

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

We usually use pathspec_item's match field for pathspec error
reporting. However "match" (or "raw") does not show the magic part,
which will play more important role later on. Preserve exact user
input for reporting.
