This is the doc string for Emacs 27.2 (the latest release):
Return string describing the version of Emacs that is running.
If optional argument HERE is non-nil, insert string at point.
Don’t use this function in programs to choose actions according
to the system configuration; look at ‘system-configuration’ instead.
But it's still a poor doc string. It should, first
of all, describe the interactive use. It should say:
With a prefix argument, insert string at point.
^^^^^^^^^^^^^^^^^^^^^^
Only after that interactive description should it
give the Emacs-Lisp description of argument HERE:
When called from Lisp, optional argument HERE
corresponds to the prefix argument.
Consider filing a (doc) bug report for this:
`M-x report-emacs-bug'.
