Comment(by ncohen):

 Hello !!!

 Here is a patch to import on top of your, to fix the documentation. These
 options are just a way for the user to compute the "longest path leaving
 from s", or the "longest path ending in t", or the "longest s-t-path"

 About the if/else, I knew it was not useful but I let it stay anyway
 thinking it would be easier to understand the code. When I look at it from
 afar, I like to see a If/Else with return lines at the end of both, which
 ensures the method ends because of this part of the code (and I like to
 preserve symmetry when there is no reason not to `^^;`). That's just me,
 if you think it's better without the "else", then let it be.

 I am really sorry you had to waste time fixing my spaces and long lines. I
 know I never paid attention to spaces, but I will from now on, and I
 thought I was wary enough of long lines, which is clearly untrue. I also
 thought I had learned not to write ``x == None`` too... `:-/`

 Here is the slight fix in the documentation you asked. If it suits you,
 the ticket is good to go.

 Thank you for your precious help, once again !

 Nathann
