Daniel Nephin 67feb8173c Add support for setting a function to handle flag parsing errors. 
The default pflag error is to only print the bad flag. This enables an application
to include a usage message or other details about the error.

Daniel Martí eb5040e69e Treat write errors in markdown doc generation 
This code was already using io.Writer, but was completely ignoring write
errors.

The most worrying part is how GenMarkdownTreeCustom used an unnecessary
buffer to then dump all of its contents on a file, and instead of
returning an error on file creation/writing, it would just exit the
entire program.
