pathspec: stop --*-pathspecs impact on internal parse_pathspec() uses
Normally parse_pathspec() is used on command line arguments where it can do fancy thing like parsing magic on each argument or adding magic for all pathspecs based on --*-pathspecs options. There's another use of parse_pathspec(), where pathspec is needed, but the input is known to be pure paths. In this case we usually don't want --*-pathspecs to interfere. And we definitely do not want to parse magic in these paths, regardless of --literal-pathspecs. Add new flag PATHSPEC_LITERAL_PATH for this purpose. When it's set, --*-pathspecs are ignored, no magic is parsed. And if the caller allows PATHSPEC_LITERAL (i.e. the next calls can take literal magic), then PATHSPEC_LITERAL will be set. This fixes cases where git chokes when GIT_*_PATHSPECS are set because parse_pathspec() indicates it won't take any magic. But GIT_*_PATHSPECS add them anyway. These are export GIT_LITERAL_PATHSPECS=1 git blame -- something git log --follow something git log --merge "git ls-files --with-tree=path" (aka parse_pathspec() in overlay_tree_on_cache()) is safe because the input is empty, and producing one pathspec due to PATHSPEC_PREFER_CWD does not take any magic into account.
