OOPs.  Now I see that in fact the leading quote is a back tick (not a single tick), while the trailing quote is a single tick.  Strange.


Might be good to spell this uncommon usage out more clearly in https://www.gnu.org/software/m4/manual/m4.html#Quoted-strings

i.e. say:

    A quoted string is a sequence of characters surrounded by quote strings, defaulting to ‘`’ (back tick) and ‘'’ (single quote), where the nested begin and end quotes within the string are balanced. The value of a string token is the text, with one level of quotes stripped off.

rather than just:

Sure, we can apply that patch (patches are easier to read in diff format, but it looks like all you did was add the strings "(back tick)" and "(single quote)" in the right places).
