The help already has the following text that applies to all the escape
sequences:

-----------------------------------------------
If the first two characters of an escape sequence are "q-" (for example,
<q-args>) then the value is quoted in such a way as to make it a valid value
for use in an expression.  This uses the argument as one single value.
When there is no argument <q-args> is an empty string.
-----------------------------------------------

So I didn't add additional help text for <q-mods>.
