A semicolon can cause following spaces to be suppressed in a string

[j4james]

For example, the code below:

"] ; ; ; ; ; [">:#,_@

should be expected to produce the following output:

[ ; ; ; ; ; ]

However, on FBBI the output looks like this:

[;;;;; ]

What's happening is the later spaces are mistakenly detected as an uninterrupted series, and a series of spaces is expected to be collapsed into one in Befunge-98. The source of the problem is the ip_move function, which has an early exit when a ; is encountered in stringmode. This prevents the spacemode (pm) variable being reset, which would usually occur at the end of the of the function.
