[PATCH] Make cell alignment more robust in gitweb blame

[Rafael Garcia-Suarez <rgarciasuarez@gmail.com>]

It appears that git-blame's returned group size can be wrong,
inducing the table display to be completely broken.

For gitweb to cope with that in a more robust manner, we can
drop the "rowspan" argument to the first <td> containing
the blame commit id, and just put empty cells instead,
whenever we have nothing to print in that column.
