Following my previous question about adjusting the footnote layout which was partially answered, I want to ask something more direct. Is there a way to get a functionality similar to \footnote+ of bigfoot package using manyfoot?
I am using the manyfoot package in the para option for the footnotes of a critical edition. I want some notes to occupy a separate line. Until now I am using the command \newline at the end of the previous note and at the end of the 'lonely' note. Unfortunately, the additional vertical space is not calculated when LaTeX is deciding the page break, so the footnote may overlap with the page number at the footer of a page. The same happens also when I predefine a new footnote command which includes \newline.
I encountered the command \footnote+ of the para option of the bigfoot package, which does exactly what I want. However, looking at the scarce documentation of the package I cannot find a way to implement it in my special case. I would like to stay to the manyfoot package, because I prefer the way its para option is working, in comparison to the bigfoot package.
Below I provide a MWE which shows the problem of the footnotes overlapping with the footer. Again, the example may seem exaggerating, but such behaviour does occur in quite a lot of my pages:
\documentclass[12pt]{book}
\usepackage{polyglossia}
\usepackage{verse}
\usepackage[para]{manyfoot}
\setdefaultlanguage{greek}
\setotherlanguage{english}
\newfontfamily\greekfont[Script=Greek,Ligatures=TeX]{Times New Roman}
\def\extrafootnoterule{\defaultfootnoterule}
\newfootnote[para]{A}
\newfootnote[para]{B}
\interfootnotelinepenalty=10000
\newcommand{\foota}[1]{
\FootnotetextA{}{\textbf{\arabic{poemline}} #1}
}
\newcommand{\footb}[1]{
\FootnotetextB{}{\textbf{\arabic{poemline}} #1}
}
\usepackage{showframe}
