Works out of the box. :-)

The suggested pipe ‘setl bt= | help’ does indeed override Vim's miserly
behavior relative to help windows..
Why?
Another quick question.. in Vimscript, what is the natural idiom to code:
if count == 0; do proc_0; fi
if count == 1; do proc_1; fi
if count > 1; do proc_n; fi
Otherwise, is there a decent tutorial on how to write functions in Vim..?
Thanks a bunch,
