After upgrading glib from 2.76 to 2.77, a t/g.t test started to fail:

    #   Failed test at t/g.t line 99.
    #          got: 'another comment
    # '
    #     expected: '#another comment
    # #'
    # Looks like you failed 1 test of 33.
    t/g.t ......................
    Dubious, test returned 1 (wstat 256, 0x100)
    Failed 1/33 subtests

The missing hash characters was an intentional change in glib
<glib#3056>.

This patch adapts the test.
