Summary: v.segment: fails to process segment if it's located exactly at the end of the input line 
Issue type: module bug
Issue status: None
GRASS version: CVS HEAD
GRASS component: vector
Operating system: all
Operating system version: 
GRASS CVS checkout date, if applies (YYMMDD): 071012


Initial Comment:
The input offsets for v.segment are as following:

$ cat offsets
P 1 1 0
P 5 1 4.6981381500000001
P 10 1 10.440307

v.segment refuses to process the last offset, saying it's not on the input line, while it falls exactly at the of the line:

$ cat offsets | v.segment llayer=1 input=line_cat output=line_cellcnt

WARNING: Cannot get point on line: cat = 1 offset = 10.440307 (line length
         = 10.440307)
         P 10 1 10.440307
