I have Cygwin installed (a rather old version; dunno which one or how to
tell). I load `cygwin-mount.el', then `setup-cygwin.el', both of which
are available on EmacsWiki:
http://www.emacswiki.org/emacs/download/cygwin-mount.el
http://www.emacswiki.org/emacs/download/setup-cygwin.el
emacs -Q
M-x man RET
Hitting TAB (with no minibuffer input) completes the empty input to the
two chars `^:'. Thereafter I can do nothing with that. Whether I type
anything after the `^:' or not, TAB just completes to `^:'.
If I instead first type `l' (as in `ls') and then hit TAB, I get [No
match]. It doesn't seem to matter what I type in the minibuffer: TAB
always says [No match].
(I can of course enter a complete command name, such as `ls' and hit
RET. `man' then works correctly. It is only the UNIX command-name
completion that is seemingly broken.
Am I missing something? I tried to debug this a bit but wasn't
successful in following what was happening. Please advise. Thx.

man.el invokes the `man' command with "^" concatenated to whatever you
typed. So the question becomes what does your port of `man' produce
if you invoke it from the shell command line like this:
man ^

You also sent a mail saying to try `man ^', i.e., without `-k'. I tried both.
$ man -k ^
^: nothing appropriate
$ man ^
No manual entry for ^
Dunno whether that helps. As I said, if I type nothing in the minibuffer and
then hit TAB it completes to `^:' with no further completion available. If I
instead type something (e.g. `l') and then hit TAB I get the message `[No
match]'.
The shell is bash. (And "man ls RET" works fine at the bash prompt.)

I guess your `man' doesn't support this option, or maybe it needs for
you to create the apropos database. In any case, "M-x man" should
handle this kind of output gracefully, which it evidently doesn't.

As Eli suggested, the question is if your man program supports the `-k'
option.
If you don't have a `whatis' database you should have a `makewhatis' or
a `mandb' program to generate it.
Then, please try
$ man -k ls
What do you get then? Does one of
$ apropos ls
or
$ whatis ls
work?
If there's no joy, please post the output of
$ man -h
$ man --help
$ man --version

I suspect you have the man program from
http://primates.ximian.com/~flucifredi/man/
In this case, essentially, "man -k ^" ends up calling "apropos ^", which
gives this output if it can't find any `whatis' database file or all
those files are empty.
Otherwise, "man -k ^" works fine, even in the 1999 vintage man-1.5g.
Also, `apropos' is a shell script, so you can easily inspect it and
debug your `man' installation.

The empty string is a prefix of "^:",

but "l" is not a prefix of "^l:".

This doesn't seem to be an Emacs bug, then. Closing.

Hm, I don't see why it follows from what Eli said that there is
no Emacs bug here. Here is what he said:
I guess your `man' doesn't support this option, or maybe it
needs for you to create the apropos database.
In any case, "M-x man" should handle this kind of output gracefully,
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
which it evidently doesn't.
Sounds like an Emacs bug, to me.
