Title says it all.
In st, long lines reflow, and when I open a file like ~/.ssh/authorized_keys in vim, a triple-click of one line selects the contents of only that physical line in the terminal, including the line break at the end. Dragging down while holding the click does select the other physical lines that the logical line was broken into, but also snags their respective line breaks.
In urxvt and others, I can open the same file in vim, triple-click a single logical line of that file that has been wrapped to multiple physical lines in the terminal, and the entire logical line is selected and yanked to primary selection.

Sounds like a feature request, that should be directly asked for on the dev mailing list, see http://suckless.org/community
