Thank you, tried and it seems to work.

I could notice only one minor issue: when making changing the terminal 
size with "Wind+arrow"with

/cygdrive/c/Program\ Files/TortoiseSVN/bin/svn log | less

less does not seem to acknowledge the new terminal size, while

svn log | less

does.
If using the mouse and resizing the terminal by hand, both commands seem 
to behave the same.
