bug#41859: 27.0.91; docstring for 'man' command

Ron Mitchell

C-h f man (describe-function "man")

brings up the docstring for the 'man' function. Several of the usages
described involve an argument string containing a space, namely

1 cat
-a chmod
-l somefile.1
-k pattern

But these argument strings cannot be entered because argument entry is
performing a completing read on available man pages.

The 'Info' documentation does not mention these usages.

Thank you for your report.

However, I cannot reproduce the problem.  The first example works
as-is for me, and the others work if I use "C-q SPC" to insert a
space.

Fair enough, I added a note to the doc string to that effect.
