Sorry about the SaveWinPosn problem -- funcsrch was on the wrong list so
it didn't have cecutil.vim bundled with it. My website's version of
funcsrch now has cecutil bundled with it.

Do the normal mode commands [[ and ][ go to the beginning and ending of
the function your cursor is in? Its possible that your style of coding
prevents vim's method of recognizing beginning-ending of functions from
working, and FuncSrch uses that.
