[Gnu-arch-users] tla changes --diffs question

[andreif]

Greetings,

I am a recent user of arch (using cygwin and tla 1.2.1) 
and I find it excellent for my needs. One problem 
though that I found is that when I do some changes 
inside some file and issue a
     tla changes --diffs
I don't see just the changes made for _some_ files, I 
see the files almost in duplicate, first the old file 
with - before each line and then the new file with + 
before each line. Normally I think I should see just 
the 2-3 changed lines, not the whole file ... anyone 
knows why is that and what can I do to solve it ?

Thanks in advance,
Andrei
