Subject: [PATCH] org.el: org-babel-load-file loads first tangle file

(org-babel-load-file): When org-mode FILE has multiple target files
for tangle blocks, `exported-file' will be set to last found
target file, which might not be the `file'.

Therefore fix for this bug is to select the last element of that
tangled file list, which is the tangle target file of the first found
tangle block, most typically the `file'.
