You should at least test the code with the fall-through condition added and see if that gets the script to run without reporting the warning (its not an error) about the unintialized variable. If it does not get rid of the warning you will know my suggestion is wrong, but if it does then your assumption of what is causing the warning could be wrong. And please note, it is a warning, not an error. Sometimes variables do have the chance of being uniitialized, which is why a default or fall-through condition is almost always a good idea.
Also, writing neat and readable code during constructions is very important, that is no excuse for writing sloppy code. Slopy code always makes tracking down bugs much harder than it should be. Its very good though that you are using "strict" and I assume "warnings".

FBB::mlm(3bobcat) OFoldStream manipulator FBB::mlm(3bobcat)
NAME
FBB::mlm - Manipulator modifying left margins of OFoldStream objects
SYNOPSIS
#include <bobcat/ofoldstream> or
#include <bobcat/ofoldstreambuf>
Linking option: -lbobcat
DESCRIPTION
The mlm class implements a manipulator that can be inserted into OFoldStream objects to modify the stream's left margin by a requested
amount. The request cannot result in a negative left margin value. If a negative left margin would be the arithmetic result of the request
then left margin 0 will silently be used.
Depending on the tab-setting of the OFoldStream the inserted value represents the number of blank space characters or the number of
tab-characters that will be added to the left margin.
The request will be processed at the next newline character or std::flush or std::endl manipulator that is inserted into the stream. If a
line is still empty once an mlm object and a flush manipulator are inserted into the stream then the new left margin will be effective at
the next word inserted into that line (cf., the example section below)
A bad_cast exception is thrown when the manipulator is inserted into an ostream that is not using a OFoldStreambuf buffer.
NAMESPACE

"
"this uses a 4 character wide left margin
" <<
mlm(-10) << flush <<
"left margin -6 changed to 0, active on this line
";
return 0;
