--------------------------------+-------------------------------
After upgrading to Ubuntu 24.04.1, noticed that the "open" action (hitting
enter) on certain files does not do anything, while others work. After
some debugging, it seems that sections in "~/.config/mc/mc.ext.ini" that
are regexp based are the ones doing nothing, whereas shell based ones are
working as expected.

Edit ~/.config/mc/mc.ext.ini file to reproduce:

Section not working (misc.sh script is not called)
{{{
[markdown]
Regex=\.mk?d$
RegexIgnoreCase=true
Open=/usr/lib/mc/ext.d/misc.sh open md
}}}

Section working (misc.sh script is called)
{{{
[markdown]
Shell=.md
ShellIgnoreCase=true
Open=/usr/lib/mc/ext.d/misc.sh open md
}}}
