hspace except at the beginning of a line

I am using the footmisc package:

\usepackage[perpage,para]{footmisc}


Every time I make a footnote, I use my own podnote command:

\newcommand{\podnote}[1]{\footnote{\hspace{-1ex}#1}}


However, I do not actually want there to be space at the beginning of a line:

How do I keep the spaces which are circled green and get rid of the one which is crossed out in red? (I don't know that this is relevant, but I am using XeLaTeX.)

How about you produce a minimal working example (MWE) so that interested parties (us!) can play around with it? –  Werner Dec 12 '11 at 19:08
irrelevant niggle -- ex should really be used only for vertical dimensions; better to use em (here, perhaps .3em for horizontal ones. –  barbara beeton Dec 12 '11 at 19:47
@barbarabeeton That's good to know. Just curious, do you have a reference for that? –  Kazark Dec 12 '11 at 20:29
@karzak The TeX Book p. 60 is one. But the recommendation is more of a conceptual one rather than substantive. Both ex and em are font-dependent measures, and either one will work. –  Alan Munn Dec 12 '11 at 20:57
@Alan's right, of course, about this being conceptual, but if you're using fonts other than computer modern (where all styles have essentially the same proportions), you might get a surprise switching, say, from serif to sans. –  barbara beeton Dec 12 '11 at 21:20

I can't reproduce your problem. Here's a minimal example which patches the footnote text code to remove the space (rather than adding a negative space in each footnote.)

\documentclass[twocolumn]{article}
\usepackage[perpage,para]{footmisc}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\@makefntext}{.5em}{0em}{}{}
\makeatother
\begin{document}

This is some text.\footnote{A footnote that has a few lines. More. Line. More. .More}
Some text\footnote{This is longer. It is longer.} This\footnote{Another one that.}
is some more text.\footnote{Another footnote that has some more lines.} Some more text.
\end{document}

This is a good corrective of my hack. However, strangely enough, it hasn't fixed my problem! See my comment about about the MWE. –  Kazark Dec 13 '11 at 21:29
So add packages from your actual document gradually to this example to see what's causing the interaction. –  Alan Munn Dec 13 '11 at 21:33
Incredibly strange...returning to my document after several months, I have somehow unintentionally fixed the problem (either that, or it is not appearing anymore randomly). Anyway, I'm going to go ahead and accept this answer. –  Kazark Feb 13 '12 at 22:07
