  (org-babel-lilypond-ly-command, org-babel-lilypond-midi-command,

  and functions.  Adapt all calls to the removed functions to use

  org-babel-lilypond-check-for-compile-error): Revert conditions to
  avoid superfluous forms.  Remove unused return values.
* testing/lisp/test-ob-lilypond.el: Do test for new variables and
  replace removed function calls with the appropriate variable
  content.  Exercise the new defcustom thoroughly.
Revert "org-clean-before-export matches non-special columns spuriously"

This reverts commit 79873390edd26a44cefc2050c7af470a7ed8fd07.
The fix was wrong and gave rise to a different problem  - see

   http://thread.gmane.org/gmane.emacs.orgmode/89945

Revert it for now, since there is a workaround for the original
problem and plan on a correct fix in the near future.

ob: Support for exporting inline source code

* lisp/ob-exp.el (org-babel-exp-inline-code-template): New
customizable variable to export inline source code (similar to
`org-babel-exp-code-template').
(org-babel-exp-code): New `type' argument to differentiate between
inline and standard code blocks.

* lisp/ob-core.el (org-babel-inline-src-block-regexp): Allow empty set
of switches and header arguments as in "src_sh[]{echo foo;}".  Also
permit spaces before them.

* testint/lisp/test-org-element.el
(test-org-element/inline-src-block-parser): Test extended syntax for
inline source code.

* testing/lisp/test-ob-exp.el (ob-exp/exports-inline-code): New
function for testing inline source code handling.  Also add three new
failing tests exhibiting unexpected results with ":results code"
switches.

* testing/lisp/test-ob.el
(test-org-babel/org-babel-get-inline-src-block-matches): Test for
inline source blocks with empty header arguments.

* testing/examples/babel.org: New sections for testing (i) exported
inline source code (used by `ob-exp/exports-inline-code'); (ii)
parsing inline source blocks with empty header arguments (used by
`test-org-babel/org-babel-get-inline-src-block-matches').

Until now pieces of inline source code were handled as standard code
blocks during export.  These changes enable them to be exported.
