string_initial
to false on no-op (#34176)
Problem: Currently undefined behavior can occur when `string_fragment()` is called with `OSC_COMMAND`. This is because when the state changes to `OSC_COMMAND`, `string_initial` is set to true. Then in some cases, directly after this `string_initial` will be set back to false before the on_osc callback is called, this leads to `term_settermprop()` never initializing the title. Solution: In all of the no-op cases in `string_fragment()` currently, we continue to the end of the function where `vt->parser.string_initial` is set to false. This change returns in the no-op cases instead since in these cases the string has not yet been terminated and sent to the callback. Note: This change also adds a test with a byte sequence from the file in #34028 that caused nvim to crash. This byte sequences is the shortest sequence I could trim down from that file that still would trigger the crash. There are also two other tests I added which validate that setting the title with OSC-0 and OSC-2 still works. Fixes: #34028

The build is CMake-based, but a Makefile is provided as a convenience. After installing the dependencies, run the following command.
make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install
To install to a non-default location:
make CMAKE_BUILD_TYPE=RelWithDebInfo CMAKE_INSTALL_PREFIX=/full/path/
make install
CMake hints for inspecting the build:
cmake --build build --target help
lists all build targets.build/CMakeCache.txt
(orcmake -LAH build/
) contains the resolved values of all CMake variables.build/compile_commands.json
shows the full compiler invocations for each translation unit.
