The best I could come up with:
folder-hook . 'set my_oldrecord=$record; set record=^; set my_folder=$record;
set record=$my_oldrecord'
folder-hook . 'push "!touch /tmp/$(echo ${my_folder} | sed 's,^=,,)-touched\n"'
The reason the solution you tried doesn't work is probably because
mutt performs shell substitution before parsing the line as said in
the manual:
"It is also possible to substitute the output of a Unix command in an
initialization file. This is accomplished by enclosing the command in
backticks (``). In Example 3.5, "Using external command's output in
configuration files", the output of the Unix command "uname -a" will
be substituted before the line is parsed."
So what shell sees is:
$ echo | sed s/=//
