v1.7.2-rc6 bug with sphinx role without link

[AntoineD]

With v1.7.2-rc6 and the following example that has a :meth: role without link (the ! before X):

class C:
    """CC.

    :meth:`!X`
    """

produces the bad change where a blank space is introduced after the second ::

class C:
    """CC.

    :meth: `!X`
    """

Curiously, this does not happen when the first sentence has only one character!

class C:
    """C.

    :meth:`!X`
    """

@AntoineD should be fixed in v1.7.2-rc7.
