We cannot have a separate section for every possible sub-class of
features.  The description of these functions is in the section named
"Shell Arguments", indeed, but this section is part of a chapter named
"Processes", and it deals with a specialized kind of quoting, so I
don't see how this will mislead, given the explicit references to
call-process and start-process.

If naming sections is important, we could rename the section to
something like "Command Arguments".
