Re: pandoc on cygwin's shell

[John MacFarlane <jgm-TVLZxgkOlNX2fBVCVOL8/A@public.gmane.org>]

findExecutable from System.Directory is being used to check
for the existence of the program and issue and error if it's
not found.

The docs for findExecutable say:

> On Windows, findExecutable calls the Win32 function
> SearchPath, which may search other places before checking

So that might be a clue about what's happening.

We could try removing that check and just letting things
fail at the point where we try to run the tex program.
But the check is nice because we can give a more informative
message early on.
