ouch! yes, that was a bad formulation once more. What I meant was the mechanism
more than an actual fma call.
manzsh is nice because it makes finding certain zsh items nicer
than default fma $manpage_name.
Would it be too costly to provide zshall as an already provided ~/man/zshall.txt.lzo
and then use the regex-power of vim to search for everything for instant access?
e.g.
manzsh() 
         {
          vim -S readoptions.vim -c 'set ft=man|set hlsearch' =( lzop -Ucd
~/man/zshall.txt.lzo )
         }       

PS: Just a little reminder, lzop -U is better, because otherwise you have the
uncompressed zshall.txt lying in ~/man, too. lzop is different from gzip, bzip here!
