# Footnotes written on the same line?

I have a long text with a lot of very short footnotes in it. There is an unfortunate amount of white space at the bottom of a lot of pages. How can I get the footnotes to write to the same line and then wrap around? This footnote code I have right now is there to force the footnotes to respect the bottom margin. Anything else can go. I tried this and it was not working for me.

\documentclass[preprint,nofootinbib]{revtex4-2}
\usepackage{lipsum}
\usepackage{etoolbox}

\footnotesep=2pt
\makeatletter
\patchcmd{\@footnotetext}
{\setspace@singlespace}{0.1}
{}{}
\makeatother

\begin{document}
\count\footins = 1000

Words\footnote{Short footnote.} words words words\footnote{Short footnote.} words\footnote{Short footnote.} words words words words words words words words\footnote{Short footnote.} words words\footnote{Short footnote.} words\footnote{Short footnote.} words words words words\footnote{Short footnote.} words words words words words.\footnote{Short footnote.}  Words\footnote{Short footnote.} words words words\footnote{Short footnote.} words\footnote{Short footnote.} words words words words words words words words\footnote{Short footnote.} words words\footnote{Short footnote.} words\footnote{Short footnote.} words words words words\footnote{Short footnote.} words words words words words.\footnote{Short footnote.}
\end{document}



Above is the code to replicate the screenshot. I actually have a lot of other stuff in my header. Just in case some of it might interfere with a proposed solution, I am also including the full header which I editted out above:

• Normally, \usepackage[para]{footmisc} would do this for you. But it does not appear to work well with revtex4-2. – Steven B. Segletes Apr 2 at 2:20
