Merge pull request #717 from stefanv/htmlnotebook_highlight_markdown Add source highlighting to markdown snippets, with a theme matching the CodeMirror one we use. This only highlights source code in blocks that are indented 4 spaces in markdown cells, leaving <pre> blocks alone. If highlight is desired in <pre> blocks, a further <code> block must be created. The visual theme matches the one used for CodeMirror as much as possible.

def which_f(self, arg):
r""" %which <cmd> => search PATH for files matching cmd. Also scans aliases.
Traverses PATH and prints all files (not just executables!) that match the
pattern on command line. Probably more useful in finding stuff
interactively than 'which', which only prints the first matching item.
Also discovers and expands aliases, so you'll see what will be executed
when you call an alias.
Example:
[~]|62> %which d
d -> ls -F --color=auto
== c:\cygwin\bin\ls.exe
c:\cygwin\bin\d.exe
[~]|64> %which diff*
diff3 -> diff3
== c:\cygwin\bin\diff3.exe
diff -> diff
== c:\cygwin\bin\diff.exe
c:\cygwin\bin\diff.exe
c:\cygwin\bin\diff3.exe
