In the -me macro set, a block defined with .(b and .)b does not have the same amount of space above and below it.

meref.me documents that it should: "All displays except centered blocks and block quotes are preceded and followed by an extra \n(bs ... space." Also, this worked correctly prior to git commit b69062693d3360efce9d4d63fac337be21e07db7 to tmac/e.tmac, applied 20 Jul 2011.

The bug can be demonstrated with the following input file:

.mso me.tmac
.nr bs 2v
Above the block.
.(b L
In the block, with surrounding space = \n(bs.
.)b
Below the block.
.br
.
.nr bs 0
Above the block.
.(b L
In the block, with surrounding space = \n(bs.
.)b
Below the block.
.br

In both cases, we should expect to see the "In the block" line equidistantly spaced from the "Above" and "Below" lines. This is so when using an e.tmac from before the Jul 2011 commit; however, when using a later one, the output contains one extra line above the block in each case.
