I propose that the information is also mentioned in 31.7::call-process
because at the same page, this is mentioned in context of another
command:

 -- Function: process-file program &optional infile buffer display
          &rest args
     This function processes files synchronously in a separate process.
     It is similar to `call-process' but may invoke a file handler based
     on the value of the variable `default-directory'.  The current
     working directory of the subprocess is `default-directory'.

	* processes.texi (Synchronous Processes): In `call-process'
	description, mention `default-directory'.
