commit r13-5281-g844eab81da3f49da88e8bb02e2b1255ba88d02b0
Author: Iain Sandoe <iain@sandoe.co.uk>
Date:   Sun Jan 22 15:17:13 2023 +0000

    Modula-2, testsuite: Remove use of concatenated paths.
    
    The original implementation for Modula-2 search paths allows things like
    '-I/path/a:/path/b'.  Such paths are not compatible with the rest of the
    compiler (in particular, the preprocessor, which Modula-2 uses).  In
    preparation for removing that idiom, this patch rewrites the cases in the
    testsuite and removes string processing where possible from lists of paths.
    
    TODO: There are some apparent discrepancies and/or extraneous insertions
    of partial include paths (especially in gm2_init_log, gm2_init_iso and
    gm2_init_pim) - to be handled in some future patch.
    
    Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>
