commit 21ad60a1d29032ab5f2a9d798ced9d1a1a8420b2
Author: Andy Wingo <address@hidden>

current-filename canonicalizes path, remove add-to-path
* module/ice-9/boot-9.scm (current-filename): Canonicalize the path, so
that the result is independent of the current directory, and so
that `dirname' can traverse up the file system, as in the
add-to-load-path example.
(add-to-path): Remove. The eval-when semantics make this macro too
tricky to explain -- people will start using it on other path-like
things, in lexical contours, whereas it only really makes sense with
load-like paths at the toplevel.
* doc/ref/api-evaluation.texi (Loading): Fix link to load-with-path
docs, and remove add-to-path docs.
