Fixes bug#44952
When inside a for loop, an 'if' statement is processed and the true part taken. Once all the commands in the true are processed, the else part is parsed, and a flag set to skip all commands in the else part. Unfortunately this flag is left on even when the if statement ends, meaning subsequent commands are also skipped.
Note: This fix does break one test, but it only worked by luck previously, so the test has been flagged similar to a number of others for the same issue as a todo for now. I'm working on sorting these out too alongside some other bugs.
