#2140: m.proj does not handle cs2cs failure

 When I input wrong proj strings to `m.proj` it calls `cs2cs` which fails
 and `m.proj` does not handle its error correctly.

 To test (you need to have `test.txt` with any content):

 m.proj input=test.txt proj_out="bla bla bla" proj_in="another bla bla bla"

 The error message is:

 Rel. 4.8.0, 6 March 2012
 projection initialization failure
 cause: unknown projection id
 program abnormally terminated
 Traceback (most recent call last):
   File "/home/vasek/dev/grass/trunk_clang/dist.i686-pc-linux-
 gnu/scripts/m.proj", line 292, in <module>
   File "/home/vasek/dev/grass/trunk_clang/dist.i686-pc-linux-
 gnu/scripts/m.proj", line 271, in main
     x, y = xy.split('\t')
 ValueError: need more than 1 value to unpack

 I haven't investigated that but checking return code is probably enough.
