Above examples are for '*', to catch EVERYTHING. I'm going to wind up with an unknown number of files in /tmp/ called file_sw_list, file2_sw_list, etc. etc.

Piping the * through ls accomplishes nothing you couldn't have accomplished without it, except possibly scrambling any filenames with whitespace in them -- backticks split across all whitespace, not newlines.
It would be a pretty freaky coincidence to wind up with filenames matching my pattern with whitespace... they're generated from unquotes variables. It could happen, and I always like to sanity check as much as possible, but that's pretty far down my list of worries.

Neither work. I get the same result.

What does the '' do? I don't understand the meaning of the blank expression, but if you say it works...
Two single quotes, not a double quote. I'm performing the operation on a file, and don't want a "backup". BSD sed is picky about this stuff (OS is OSX).

Why are you escaping a space?
Because there's a literal space in the pattern I'm matching?
In any case, it turned out to be a second pattern that matched '^Software\ Update' that was so close to the top I didn't notice just a couple of lines missing :-)

uri_urn - URI utilities, URN scheme
SYNOPSIS
package require Tcl 8.2
package require uri::urn ?1.1.2?
uri::urn::quote url
uri::urn::unquote url
_________________________________________________________________DESCRIPTION
This package provides two commands to quote and unquote the disallowed characters for url using the urn scheme, registers the scheme with
the package uri, and provides internal helpers which will be automatically used by the commands uri::split and uri::join of package uri to
handle urls using the urn scheme.
COMMANDS
uri::urn::quote url
This command quotes the characters disallowed by the urn scheme (per RFC 2141 sec2.2) in the url and returns the modified url as its
result.
uri::urn::unquote url
This commands performs the reverse of ::uri::urn::quote. It takes an urn url, removes the quoting from all disallowed characters,
and returns the modified urls as its result.
