Apparently the `\zs` token does not match characters if they are already
part of a syntax match. For example in `[^0][^1]` only the zero footnote
is matched. Fix this by using a positive lookbehind that does not have
this limitation.
Additionally, use a negative lookahead for the colon to make the pattern
slightly more readable, since it does not need the end-of-line check.
Conceal numeric footnotes with superscript numbers. The whole thing is a
bit of a gimmick since only single digit numbers are concealed but I had
this idea for quite some time and wanted to execute it.
When not put into the `after/` directory, the matches are overwritten by
the `markdownFootnote` group.
WinResized was introduced rather recently with vim patch 9.0.0917 /
neovim v0.9.0 via commit 4571ba4d0a52 ("vim-patch:partial:9.0.0917: the
WinScrolled autocommand event is not enough (#21161)").
From :h :Man:

Since I actually don't like `g:man_hardwrap=0`/`MANPAGER=999` (e.g.
scrolling can be a mess with very long wrapped lines), add an
autocommand that is meant to reload the manpage through `:edit` after
every resize, so that its hard-wrapping adjusts to the new size.
This is slightly hacky, but does its job quite well.
Move the man.vim into after/ftplugin so that it overwrites the `set
wrap` of the global ftplugin, which I want turned off, since it messes
with the buffer shortly when resizing.
