'cedit' setting, set the default, do the work of the function, then
restore the original setting before returning.

first coffee--but I don't think you understand the problem. The
'cedit' key is used to open the command-line window. The plugin
writer doesn't want to open the command-line window. The plugin
writer doesn't even care that command-line window exists. All he
wants to do is execute a normal-mode command that ends with an
exe 'norm! /\%'.leftcol."v\<Esc>"
which :help says should behave as follows in that context:
<Esc> When typed and 'x' not present in 'cpoptions', quit
Command-line mode without executing. In macros or
when 'x' present in 'cpoptions', start entered command.
Instead of getting that documented behavior, the normal-mode command
is interpreting that <Esc> as the cedit key and entering the
command-line window. The plugin writer just wants to execute his
command. I don't see any way to escape that <Esc> to make it do
what :help says it does and not enter the command-line window when
'cedit' is set to <Esc>.
I think if the &cedit character was escaped with ^V as you
suggested, that would place a literal &cedit in the text, which is
not what the plugin writer wants, either.
The only solution I see, without modifying Vim as I suggested, is to
save and restore 'cedit' as I also suggested.
