Description
help2man splits the option name and its description at two (or more) spaces. When using a longest option with an argument there is only one space between "arg" and the option description text.

for options without arguments there are at least two spaces, so the bug is in the probably unwanted special behavior for options with arguments

OK, I looked into the source and found out that two spaces are intended according to a comment in options_description::get_option_column_width().
I found more subtle bugs in this function and fixed them as well, the function should now also be easier to understand.
Beware: the patch is only compile-tested with vim-youcompleteme, I don't have a test infrastructure set up for boost.

I've had the time to actually build it and fixed an off-by-one error (attached).
Timo,
thanks for your report. However, at presents I'm a bit reluctant to change output format to accomodate a particular tool. I don't think this was a concern anybody raised previously.
