Thanks, installed on master, and closing the bug.  I added a comment
there regarding the use of shell-quote-argument, for posterity.

Hello,

In Gnu/Linux there is a binary named "[" in /usr/bin/, and it has a man
page I can read in a terminal using "man '[(1)'".

Requesting the man page in Emacs using `man' is broken, however:

  M-x manual-entry RET [ TAB

echoes "[No match]" - this is the first problem (the failing
completion).

C-g, let's try differently:

  M-x manual-entry RET TAB [ TAB

(that's the same as before but additionally requesting all candidates
before writing in the minibuffer) suddenly completes to "[(1)" as
expected.  But when confirming with RET the man buffer only has these
contents:

| /bin/sh: 1: Syntax error: "(" unexpected
|
| process exited abnormally with code 2

That's the second problem.

Oh, and M-x woman [ RET works as expected.


TIA,

Michael.
