If the else clause is intentionally missing, some folks prefer to use
when instead of if to advertise that fact (see some surrounding code
for example).  In this case the additional if should be rolled into
the condition check of the former when anyway (and let-bind the result
to avoid the duplicate file-name-directory call).  The conditional is
actually superfluous since we can short-circuit from the and.

A patch to that effect has been installed in 063c8b03b7.

[O] :mkdirp without path specifier

2014-05-01 Thread Michael Weylandt 
If it intended that setting :mkdirp yes should break tangling with 
'directory-free' file names?

I.e., should
#
#+TITLE: test
#+BEGIN_SRC python :mkdirp yes :tangle test.py
print 1+2
#+END_SRC
###

tangle without error? 

It currently doesn't because (file-name-directory test.py), which is nil, 
gets passed to make-directory, which throws an error. 

The manual is ambiguous, stating only that the arg to :tangle is interpreted as 
a path. A strict reading says this shouldn't work, regardless of :mkdirp, since 
we're not giving a path, but I think the understood ./ of :mkdirp no is 
reasonable. 

I'm not in a position to do so now, but can send a one-line patch to fix 
tonight if wanted.
