style syntax. There still needs to be work done on the regexps for
recognising #+srcname lines possibly with/without parenthesised
arguments. This change makes org-babel-block-name return nil rather
than fail when it doesn't find a src block head (e.g. in a #+lob
line), which seems sensible.
The sbe test table is failing half-way down at `simple ruby
arrays'. For some reason it is making a mini table ("| |") to the
right hand, and point keeps jumping out of the table. My ability to
debug sbe-related stuff is hampered by me not understanding the
code (I need to learn about macros).
