[PATCH] D154130: [lit] Avoid os.path.realpath on Windows due to MAX_PATH limitations

[Joel E. Denny via Phabricator via cfe-commits]

jdenny added a comment.

If the `%>` feature is going to remain (depending on, for example, the answer to @tahonermann's question <https://reviews.llvm.org/D154130#4486898> about modulemap), please:

1. Add it to the lit documentation at https://llvm.org/docs/TestingGuide.html#substitutions and https://llvm.org/docs/CommandGuide/lit.html#substitutions.  (Aside: I wish someone would reconcile those lists.)
2. Consider whether there's a clearer syntax.  For example, we already have `%{/t:regex_replacement}`.  What about `%{t:real}` and `%{/t:real}`?
