v.support

Problem 1:

v.support seems not to work well with assignment of category
values to areas with some shapes like the one below:

*****************
* *
* *
*-------- *
* *
*****************

the line inside areas like ----------- seems to cause the problem
is there any program deleting such lines?

Problem 2

is there any program for merging adjacent areas with the same
attributes values like two below:

***************
* *
* att=12 *
* *
**************
* *
* att=12 *
* *
***********
