    gdb/source.c: Fix matching path substitute rule listing
    
    The check for the source (or "from") directory snippet in listing
    matching path substitution rules currently will not match anything
    other than a direct match of the "from" field in a substitution rule,
    resulting in the incorrect behavior below:
    
    ...
    (gdb) set substitute-path /a/path /another/path
    (gdb) show substitute-path
    List of all source path substitution rules:
      `/a/path' -> `/another/path'.
    (gdb) show substitute-path /a/path/to/a/file.ext
    Source path substitution rule matching `/a/path/to/a/file.ext':
    (gdb) show substitute-path /a/path
    Source path substitution rule matching `/a/path':
      `/a/path' -> `/another/path'.
    ...
    
    This change effects the following behavior by (sanely) checking
    with the length of the "from" portion of a rule and ensuring that
    the next character of the path considered for substitution is a path
    delimiter (or NULL). With this change, the following behavior is
    garnered:
    ...
    (gdb) set substitute-path /a/path /another/path
    (gdb) show substitute-path
    List of all source path substitution rules:
      `/a/path' -> `/another/path'.
    (gdb) show substitute-path /a/path/to/a/file.ext
    Source path substitution rule matching `/a/path/to/a/file.ext':
      `/a/path' -> `/another/path'.
    (gdb) show substitute-path /a/pathological/case/that/should/fail.err
    Source path substitution rule matching `/a/pathological/case/that/should/fail.err':
    (gdb)
    
    Also included is a couple of tests added to subst.exp to verify
    this behavior in the test suite.
    
    gdb/ChangeLog:
    
            * source.c (show_substitute_path_command): Fix display of matching
            substitution rules.
    
    gdb/testsuite/ChangeLog:
    
            * gdb.ada/subst.exp: Add tests to verify partial path matching
            output.
    
    This was tested on x86_64 Linux.
