📄 Description

#12348 introduced an off-by-one bug. While the NormalizeCommandLine loop
should exit early when there aren't at least two arguments to be joined,
the final argument-append needs to happen even if just one argument exists.

This commit fixes the issue and introduces changes to additionally monitor
the early loop exit, as well as the call to ExpandEnvironmentStringsW.
