[Monotone-devel] Possible bug in 'mtn cat'

[Marcin W. Dąbrowski]

Hi.

Today I've found something weird. As image says more, and
working example is even better, with not further ado:

----- BEGIN BATCH -----
mtn version --full
mtn -d mtn.mtn db init
mtn -d mtn.mtn setup . -b mtn.bug.cat
echo x> example.txt
mtn add example.txt
mtn ci -m "Added new file."
mtn cat -r h: example.txt > example-check.txt
xxd -g8 example.txt
xxd -g8 example-check.txt
----- END BATCH -----


On my machine, it gives:

Why the 0x0d (\r, CR, etc) gets doubled?

PS: Running mtn cat --debug doesn't show anything interesting.
